Posted on by Vinit

Hi,

I want to show a popup to user to get some input. i have created a HTML webresource with 'input' element and used Alert.showWebresource() method to open a popup with input box. However, when i enter any value in that input box of HTML webresource, i'm not able to get it though javascript code.

i have used document.getElementById but it failed.

Is there any way to get the value available in input box of HTML webresource?

Hi,

Try window.parent.document.getElementById() instead of window.top.document.getElementById()

You can do it by creating a callback function and pass it to window.showModalDialog() or window.open() where you open the webresource, get the data and pass it back to the callback function where you make use of the data.

So you will have to open a dialog from the JS that is executing on the form...

Thanks Iswarya,

I have tried both the ways, but it is still returning null value.

Its not able to read the value present in HTML webresource.

Thanks ddelic,

window.showModalDialog is unsupported and window.open is opening the window in new tab.

But as per my requirement, I need to show a popup to get the input from user.

Hi,

try to use Prompt for getting user input

function myFunction() {

debugger;

var txt;

var person = prompt("Please enter your reason for 'Rejection':");

if (person == null || person == "") {

txt = "User cancelled the prompt.";

} else {

txt = person;

}

Xrm.Page.getAttribute("new_rejectreason").setValue(txt);

}

I see you are using alert.js -> maybe you should consider using Alert.showDialogProcess method then and make use of callback function

How are you opening the HTML web resource?

The is that there is not callback from the web resource, which is why you can't return the value.

Did you try parent.Xrm.Page.getAttribute("new_field").setValue(textValue)?
