javascript onchange event

Question

User-125499312 posted

I have a textbox that I amm assigning a value to it via javascript without the user actually typing in a value.

I would like to fire a javascript function after the value get put into the textbox.

the onchange event only fires when you actually type in a value.

Thanks for help

Hi!

Why not call the function directly after you assign the value to the textbox? Since you want to fire (execute) a javascript function after you assign value to a textbox, I think you should just call the function directly after assigning value to the textbox and not rely on the onchange event.

Hi,

instead of onchage event, you can use onpropertychange event...

like <asp:textbox......  onpropertychange="yourfunctuion();">

Hi,

you can also use onblur method.

like <asp:textbox......  onblur="yourfunctuion();">

Hi,
I have a similar problem and can’t seem to find any real help regarding this.

i have a page that uses and iframe to “lookup” values and then post it to the parent form/page using java script.
sample code:
function postParent()
{
// parent objects (Mariner page)
var parName = parent.document.getElementById(’myTextbox′);

var parIframe = parent.document.getElementById(’myFrame′);

// iframe objects
var oName = document.getElementById(’txtNameOnFrame’);

// import the select values
parName.value = oName.value;

// hide the iframe
parIframe.style.height = 0;
parIframe.style.visibility = “hidden”;

}

My issue is that when I post the page to store the data, the value on the textbox populated using code, is blank. however, if i type any additional text into the textbox, then it posts the data correctly.
i tried onblur, this.value=this.value etc. but all with no success.
Can you see something that i don’t or can this not be done.

Regards

Danny
