How to allow only Number(0-9) in jsff ADF

Hello

InputText expected than numbers. I tried to implement using ClientListener and bottom of javascript but I am able to enter special characters! @# $% ^ & * ().

How to get there?

< af:inputText label = "" days after project actual start: ""

ID = "it10.

value = "#{ReviewDeadlineRuleEvents.daysAfterActProjectStart} '"

maximumLength = "#{bindings." DaysAfterActProjStart.hints.precision} ">"

< f: validateLongRange minimum = "0" / >

< af:convertNumber groupingUsed = "false".

model = ' #{bindings. " DaysAfterActProjStart.hints.format}"/ >

< af:clientListener method = "filterForNumbers".

Type = "keyDown" / >

< / af:inputText >

JavaScript:

< af:resource type = "javascript" >
function filterForNumbers (evt) {}
get the source of the event, ADF Faces, InputText.js
var inputField = evt.getSource ();

oldValue var = inputField.getValue ();

var ignoredControlKeys = new Array (AdfKeyStroke.BACKSPACE_KEY, AdfKeyStroke.DELETE_KEY);

set the range to exclude in the entry field
var minNumberKeyCode = 48;
var maxNumberKeyCode = 57;
var minNumberPadKeyCode = 96;
var maxNumberPadKeyCode = 105;
key pressed by the user
var keyCodePressed = evt.getKeyCode ();
If it is a control key, do not delete
var ignoreKey = false;

for {(keyPos to ignoredControlKeys)

If (keyCodePressed is {ignoredControlKeys [keyPos])}
ignoreKey = true;
break;
}

}

return if the key should be ignored
If (ignoreKey == true) {}
Returns true;
}
filter entry keyboard
If (keyCodePressed & lt; minNumberKeyCode: keyCodePressed & gt; maxNumberPadKeyCode) {}
value set by the previous value
inputField.setValue (oldValue);
no need for the event to be propagated to the server, so don't cancel
He
evt. Cancel();
Returns true;
}
If (keyCodePressed & gt; maxNumberKeyCode & amp; keyCodePressed & lt; minNumberPadKeyCode) {}
value set by the previous value
inputField.setValue (oldValue);
evt. Cancel();
Returns true;
}

}

< / af:resource >

Thanks in advance.

Always mention your jdev version.

In this input text example box allows you to enter all the characters with the error message but my requirement is that is should not allow anything to enter outside numbers.

You must use the javascript solution.

For example:

function filterForNumbers(event) {
    var ignoredKeys = new Array(AdfKeyStroke.BACKSPACE_KEY, AdfKeyStroke.DELETE_KEY);
    var keyCode = event.getKeyCode();

    if(ignoredKeys.indexOf(keyCode) > -1){
        return;
    }

    if(keyCode < 48 || keyCode > 57){
        event.cancel();
    }
}

You will probably have to trigger this function on keyPress and not on the keyDown event.

And if concern is security, and then you combine it with check(af:validateRegExp) on the server side.

    Hi Matt,

    This forum is for MSE who cannot restrict access of Web site you want.

    One of the possible methods that comes to mind uses the Parental http://www.windows-help-central.com/parental-controls-in-windows-xp.html may control with Windows Live Family Safety http://explore.live.com/windows-live-family-safety?os=other (according to the version of XP and whether or not you have a workgroup or domain LAN).  When you set up, allow *.gov, but reject all other types you can imagine (I don't think there is a way to allow only .gov, but you can exclude most if not all of the other busiest - check domain name registrars to get a list of options).  If you use a domain, way to go would be with a custom domain group policy to restrict access on all of the network (except perhaps the server or individuals of special category in Active Directory if you want).

  • How can I allow only a specific list of employees to receive marketing emails, but exclude all others in the same company?

    We have an important customer who said they don't want their employees who receive emails from marketing except a specific list of their management team. Also, we do not want the employees of our customers who decide to opt-in to receive emails from our registration page if they use their work email address.

    How can I allow only a specific list of employees (management team) to receive marketing emails, but exclude all others in the same company?

    One way is to create a list of sharing, "company A does not include." Build a program in the program generator with a charger that looks for the domain "company A". Place a filter in the program on a decision rule with the emails to management teams; If they are in the filter (that is, they are on the management team), remove them program, if they are not (that is, they are not the management team), add them to the list of sharing "excludes company A. Then you can add the list of sharing "Company A excludes" as an exclusion on your segments or implement a model that they will automatically as an exclusion.

    They oppose all non management team emails? If they are, as an extra precaution, you could add the "exclude company A" to master exclusion list.

  • Writing javascript code to a box that when activated, it removes the read-only attribute in another area and allows a number against the default calculation that occur.

    I have an order entry form that calculates a sum of $ calculate markup by a formula in the section rating field simplified in the field on the tab properties.  The field of markup is set to read-only.  I also have a configuration like a checkbox.  If the user selects the check box, I need this field of markup to become editable (remove the read-only attribute) to allow a number to be entered in the field.  I guess I'd also need programmatically delete the calculation in the simplified field notation when the box has been activated.  I think I need a custom java script to trigger on mouse enter?  I could also use some help setting java script.  Someone has it all done something similar?

    Thanks in advance.

    You can no longer use the method of the "simple field notation" If you change the field in certain situations. The following script assumes that you just want to add two fields and use 25% of this amount as your markup, unless the box named "CheckBox" is checked, then the field will become editable and you can enter what you want:

    // get the state of the "CheckBox" - modify the field name to match your form
var cb = this.getField("CheckBox");

if (cb.value == "Off") {
    // Checkbox is unchecked, so perform the calculation and make sure the field is read-only
    event.target.readonly = true;
     // simple calculation - you need to modify this
    var result = (Number(this.getField("Field1").value) + Number(this.getField("Field2").value)) * 0.25;
    event.value = result;
}
else {
    // Checkbox is checked, so do not modify the value, set the field to read/write and let the user enter anything they want.
    event.target.readonly = false;
}

    Hi all

    Someone managed to create a responsibility to allow only the password resets? The idea is to assign this responsibility to our office staff help password reset requests. They will not have the opportunity to do anything outside of search for users, and then reset the password. This would allow a large number of the number of tickets to be processed directly by our help desk staff.

    Any information would be greatly appreciated.

  • Allow only smartphones via anyconnect

    Is this possible? The goal is to allow only smartphones/tablets; No full blown laptop os'.

    If you have the anyconnect essentials and the mobile anyconnect license would it as simple as ordering "no anyconnect essentials". According to the docs this only disables anyconnect essentials, but leaves the license intact. I hope that this would mean that the anyconnect for mobile would continue to operate. Or maybe there's another way to do this?

    Unfortunately I do not have the freedom to test and cannot find it in the documentation.

    ~ Thank you

    "no anyconnect essentials" disables this feature of license for the AnyConnect Premium license.

    AnyConnect for Mobile requires one or the other license to operate.

    To apply a restriction of device type, you would normally use Dynamic Access Policy (with AnyConnect Premium) and the Cisco Secure Desktop feature. However, CSD is only supported on Windows / OS X / Linux. (Example)

    Another way, you could do it would be with the device certificates. Check endpoints for the presence of a certificate (which you would need to deploy) and only allow valid wallet certificate devices to be authenticated. That's how it is (among other things) with Cisco ISE. ISE relieves the pain somewhat by deploying the certificate under the device / user integration. Do it with only ASA, should allows you to use a deployment of certificate 3rd party (or possibly PEIE, but I don't think that you could argue the mobile device in the CEP inscription).
