Set the variable to the text entered in a text box

Hello. I have 2 text boxes on a form that the user can type in numbers. I just want to add the numbers that they typeRegeditdans together and the response of output. I'm a simple and will get more complicated with my calculations later. I've done the calculations to work if they are entered in a database, but we need to work on the fly based on what the user has typed in the text boxes.

I am only able to set the text of the box and their output values, but I can't bring it to add up. I have some javascript that displays what has been typed in areas using CFSet. Is it the way I should write this? Is it possible to condense the javascript, or I have to separate each set of code text box on? Is there another way to do this simple calculation with just Cold Fusion, or do I have the javascript to enter numbers that are entered in the text boxes? Here is the code I have below. If you delete the CFset price and output price, you will see that this code generates areas of text X and Y. thank you for your help.

< name cfparam = "url. X"default =" ">

< name cfparam = "url. "By default Y" = "" >

< cfoutput >

< script type = "text/javascript" >

var pageSoumettre = ' #jsStringFormat (url. X)#';

function appenX() {}

document.getElementById('submitLink').href = '? X=' +

encodeURIComponent)

(pageSubmit.length? pageSubmit + ',' :'') +)

document.getElementById('X').value);

}

var pageSoumettre = ' #jsStringFormat (url. Y)#';

function appenY() {}

document.getElementById('submitLink').href = '? Y=' +

encodeURIComponent)

(pageSubmit.length? pageSubmit + ',' :'') +)

document.getElementById('Y').value);

}

< /script >

< name cfform = "theForm" action = "" # "method ="get">"

< cfinput type = "text" name = "X" id = "X" value = "" > < br / >

< cfinput type = "text" name = 'Y' id = 'Y' value = "" >

< input type = "submit" id = "submitLink" onclick = "appenX (); "onclick ="appenY (); "value ="Update">

< / cfform >

< cfset X = #url. X # >

< cfset #url =. Y # >

< cfset price = X + Y >

#X # < br / >

#Y #.

#Price #.

< / cfoutput >

Mixture of Javascript with Coldfusion is unnecessarily complex. If all you need is to add the value of two form fields, then just Google javascript add form fields and you will get a lot of suggestions.

  • Set the text box

    Could someone tell me how I can get the blocks of text that are automatically adjusted to changes in the margins?  After creating a document and put in all the stories and images, we realize that an adjustment is required to the margins, which would in turn ensure that we would need to set the text of the documents field to align with the new margins.  We can do it by hand, but it will take time and also complex that InDesign is that it seems that we should be able to do this automatically, but how?

    Depends on how you set up the document in the first place. If the text block is aligned with margin guides, allow the adjustment of the layout and change the margins of the master page.

  • CS6 inDesign when the text box is set it is not adapt the text with it

    Hi Adobe community.

    In the past, I have been using Adobe CS5.5 and when you use Indesign I would like to make a text box, text entry and when I need the text box to be narrower, as I'm adjusting the box with the text selection tool would be admissible and move and adjust to fit within the box like you were changing the text box. So, you could see the text as you did the box around it more small.

    Now, I just went to do the same in InDesign CS6 but when move the text box, it simply moves the text and the text moves with it (do not meet with setting the text box), so I'm left guessing where the text will be sitting and it provides a few going until she I understand...

    So what I am asking, is there a box I need check preferences or something in CS6 so that text moves I adjust its bounding box, as it moves in CS5.5?

    Please help because it really bugs me!

  • Script to change the fill color of the text box when the text is entered

    Hi all

    I'm working on a creation of a PDF form with a lot of text fields and I was wondering if it is possible to write a JavaScript script that will set the background color of the text box to white If the user enters any textand transparent otherwise. Any ideas?

    Thank you

    Of course you can. You can do this during the Validate event, for example:

    Validate the script

    event.target.fillColor = event.value? Color.White: color.transparent;

  • the value of variables in the text box.

    I write a code that has a function of function there is a table of the different variables of table, values come from Server I'd like
    Enter this value of var in the text box.

    It's like in the code file is like this

    public void mainMenu (rcvParametersArray:Array): void {}

    var IndianMenu:int = rcvParametersArray [0];
    var chainesMenu:int = rcvParametersArray [1];
    }

    Assuming a component textArea on the stage, something like the following should work (composed an array to pass to the):

    var theMenus:Array = [1,2];
    mainMenu (theMenus);
    function mainMenu(rcvParametersArray:Array):void {}
    var IndianMenu:int = rcvParametersArray [0];
    var chainesMenu:int = rcvParametersArray [1];
    arrayDisplay.text = IndianMenu + ', ' + chainesMenu;
    }

    However, it seems that he might extend to several items, I was wondering if maybe you don't want to have an array of arrays so that the menu name is incorporated with its index or regardless of the other properties are associated with. Maybe not, but I thought that I would say something like the following in case it is useful

    var theMenus:Array = new Array ({name: 'Indian', index: 1}, {name: 'Channels', index: 42});
    mainMenu (theMenus);
    function mainMenu(rcvParametersArray:Array):void {}
    for (var i: int = 0; i< rcvparametersarray.length;="">
    arrayDisplay.text += rcvParametersArray [i] .name + "" + rcvParametersArray [i] .index + "\n";
    }
    }

    Finally, if the values in the table of your original paintings are numbers or integers (ints), you can convert them to strings before displaying using the toString() function, unless they are be concatenated with an existing string.

  • Set the focus to the text box of the embedded NumericStepper control

    I have an application that requires I use NumericStepper edit control as ItemEditor of a DataGrid column.

    I have two problems that I can't seem to overcome, one being the result of the solution to another:

    (1) I need to instantiate the component NumericStepper during execution, because I don't ' know advance what columns it will require.  More important still, I need to specify default attributes (styles, min, max, width, etc.).  I can't understand how to specify these attributes other than in a .mxml file.  To handle this, I have crreated a component 'wrapper' that's an HBox with a NumericStepper inside her, and I can specify my attributes on the tag NumericStepper.

    (2) now that I did #1 above, although, when I click a DataGrid cell that uses this component editing, the editor comes back but the text box is NOT centered, which means that the user must click a second time if he wants to type a number.  It's very irritating, but I do not know how to manage the focus such as when my HBox-with-embedded-NumericStepper' control rises, it concentrates and its selected data, NumericStepper, just as the 'base' is.

    So, my questions are:

    (1) can I somehow assign property values to a standard when executing NumericStepper, so that I can avoid using my built-in custom control HBox?

    (2) how can I manage the focus so that when my control HBox is in place, the text box is selected and fucused?

    That sounds confusing, but I have a small program to demonstrate this.  The "QtyBad" column uses my own NumericStepper HBos-based and not to be put in the correct focus when activated.  The "QtyGood" column has demonstrated APPROPRIATE behavior, as exposed by the native NumericStepper component, but I can't specify additional attributes / s on this subject.

    Here are all of the program - called "DGNumStepperDemo" - here:

    DGNumStepperDemo.mxml

    {
    CDL of the var: Array = new Array();
    var dgc:DataGridColumn;

    DGC = new DataGridColumn ("QtyBad");
    dgc.dataField = "Qty";
    DGC. Width = 75;
    dgc.itemEditor = new ClassFactory (EditorDGNumericStepper);
    dgc.editorDataField = "value";
    cols.push (DGC);

    DGC = new DataGridColumn ("QtyGood");
    dgc.dataField = "Qty";
    DGC. Width = 75;
    dgc.itemEditor = new ClassFactory (mx.controls.NumericStepper);

    dgc.editorDataField = "value";
    cols.push (DGC);

    DG1. Columns = cols;
    DG1. DataProvider = gridData;
    }

    []] >
    < / mx:Script >
    < mx:NumericStepper id = "itemQuantity" value = "{data.". Qty}"minimum maximum ="0"="100"/ >
    < / mx:HBox >

    If anyone who bothers to run it, you can see what I mean about the focus problem in the QtyGood and QtyBad columns.

    Any help is appreciated!

    Quick response to the #2 is to change the EditorDGNumericStepper.mxml to the following:

    
    http://www.adobe.com/2006/mxml"
               verticalAlign="middle" paddingRight="4" paddingLeft="4"
               verticalScrollPolicy="off" horizontalScrollPolicy="off"
               creationComplete="focusManager.setFocus(itemQuantity)">
         
              
         
         
    
    

    The only thing I did was put the NumericStepper to 100% width so it fills the column like the standard NumericStepper and it looks a bit better and I added a creation complete event handler that sets the focus to the NumericStepper.  I tested it and it will be emphasis each time on it like a standard stepper.  There may be a more "preferred" way, but it's simple and effective.

    On the #1 question, you want to change the properties, styles, etc. of a NumericStepper standard once it has been added to the data grid?

  • Test whether the text box is empty - tip action

    Hello

    I have a form that the user is required to fill out. When the user tries to advance to the next slide, I would test to check that none of the text boxes are empty.

    Ideally something like;

    If ((Textbox1) == null) {}

    See the legend of failure

    } else {}

    continue

    }

    I know you can use advanced actions but I'm unable to set the null value. I even tried to create a new variable and leave empty and tests textbox against that, but apparently not worked either.

    I'm probably missing something simple as I am very new to Captivate.

    Hello!

    I had the same problem.

    The user must enter his name.

    I preset the variable of the text using the feature box "what would happen if you reach this slide." You can find it if you double-click the slide with your text box, and then find the area of "navigation". I have a German version of the A4 the names of functions differ...

    Declare the variable of your text box we'll say "ABC123".

    With a collateral action, you can check if the text inside the variable passed as ABC123 to something else:

    If

    variable_name is not equal to ABC123

    then

    ...

    on the other

    ...

    If the variable is always ABC123 I jump to another slide with an error message.

    An example, which you can find here:

  • cannot delete the text box entry - break cp8

    I have two text input boxes and a button smartshape on a slide.

    Text entry areas require username, stores the responses into variables. The button moves to the next slide. I don't want the button to pause the slide, but not text entry areas.

    When I uncheck the 'pause after"in the properties of the input synchronization for each of the text boxes, the break is always carried out for each. In fact, icon pause shows still on the layer of the timeline for each as well.

    The result is that my slide stop 3 times instead of once:)

    It's Captivate 8, sensitive project.

    It is for some a bug in CP8, in previous versions you can change the time of the break, but you can disable it. Must be a design fault, using the same properties of timing for each interactive object to CP8 (to make it "clear").

    For me, it makes sense that you can't disable pause in BER, since it must wait for an input from the user. It's the same for question slides, no way to disable the pause, you can move only. For BER you can move with the synchronization properties, which is not yet the case for Question slides where you (still) that slide on the Timeline can move the point of interruption.

    Why should you get this button? If it is designed as a next button, do you want so that it can move without entries in of the TEB? Then set its action to 'go to the next slide", not to continue?
