The error i am getting is "run time exception Object Excepted "...

My code of javascript is given below,

function CheckFilterDates(f)
{
 
  if(!(f.ctl00_ContentPlaceHolder1_txtsortFrom.text==""))
    {
 
        if(f.ctl00_ContentPlaceHolder1_txtsortTo.text=="")
        {
            alert("Please Enter The Value of Remaining Date");
            return false;
         }
     }
 
     if(!(f.ctl00_ContentPlaceHolder1_txtsortTo.text==""))
    {
        if(f.ctl00_ContentPlaceHolder1_txtsortFrom.text=="")
        {
            alert("Please Enter The Value of Remaining Date");
            return false;
         }
     }
}
 

I have also used "getElementById" but it's still giving me same error...

[gits]

do you have a formelement with:

name = "ctl00_ContentPlaceHolder1_txtsortFrom"

in your case or:

id = "ctl00_ContentPlaceHolder1_txtsortFrom";

when you use getElementById();?

kind regards

Yes my formelement id is

 id = "ctl00_ContentPlaceHolder1_txtsortFrom";

and i am using f.id, instead of this i also tried the getElementById() but in the both case i am getting the same error....
so where is the problem ??
i am calling this function with button's onclick event...

[gits]

in case the id is correct, which you could check when having a look at the rendered page (just use view source in the browser) and search for your formelement with that id ... then:

var id = 'ctl00_ContentPlaceHolder1_txtsortFrom';
var n  = document.getElementById(id);
 

have to give you a reference to that node for variable n. could you please post the call of document.getElementById() and the rendered code for your node?

kind regards

Ya it's true, but the same thing is working well with button outside of <fieldset> means the button which is outside the legend, the problem is not with the id because if i callls simple blank function without body then also it giving me same error.... means if i calls

function CheckDate(f)
{
             alert("Date");
}
 

then also it is giving me same error...
so where is the problem ? please suggest me where is the problem ?

[gits]

hmmmm ... is any other action triggered with the button click? do you have a testpage where i could have a look at? how are the event-handlers attached to the buttons?

kind regards

[malav123]

kind regards

No, Only one action is triggered with Button click.... that is

 
btnFilter.Attributes.Add("Onclick", "return CheckFilterDates(this.form)")
 

and my button is within the fieldset,

<fieldset>
<legend>Filter</legend>
<asp:Button ID="btnFilter" runat="server" Text="Filter" />
</fieldset>
 

I am not getting from where this error occurs....

[gits]

are you sure that your parameter this.form is correct here?

[malav123]

are you sure that your parameter this.form is correct here?

Yes i am using this.form with another button attributes and working proper.... i have also tried only this but still getting same error....

[gits]

what about using no param at all? does the problem persist in that case? ... could you try the application in FF and have a look at the error-console ... probably we get a much better error description with that ...

kind regards

[gits]

kind regards

[malav123]

have you tried it now? what does the console says? ...

kind regards

Yes it works well in FF, so now how to debug my problem in IE...? and this problem is only occurs with button which is within the legend...

[gits]

... do you have a link to a testpage? or could you post the html source when it is laoded to IE ... have a look at view source in the browser and paste the code here ... so that we may see the code and test it?

Sorry that i don't know about how to post code in proper format...

[gits]

hi ...

i just cannot see something wrong ... could you give the link to the testpage ... so that we could test it online?

kind regards

[malav123]

kind regards

Means about which link you are asking ? we still not put it online, my project is still in developing face...

[gits]

Yes i have link for that page ...

sorry ... i thought you had a link to test the page online ... so that problem seems to be strange ... let me summarize:

1. IE gives you the error FF does not und works properly?
2. only when the button is placed within the fieldset? even when you call an empty handler function?
3. the only javascript code that gets executed onclick is the onclick-handler function assigned to the button?

did you test it on different machines and IEs? may be its a problem with your local IE installation?

kind regards

Hi,
You was right now my all validation for buttons giving me same error that is js runtime error... so what can i do, should i reinstall IE ???

[gits]

nope not yet :) ... could you get alerts in your validation functions? if that is the case you should start to trace the elements that are used ... i mean whenever you use a html-node-reference just alert its tagName to see whether this works or not ... may be you could track the error this way? since you don't have a test-link i don't know what i could recommend instead ... since IE's js-debugging abilities are very limited ... may be tha MS IE Script Debugger may help?

No i am not getting any alert also...in all the reference nodes it's giving the same error that is runtime js error... even if i calls simply without parameterized function and if i puts simple alert then also i m getting the same runtime js error...

[gits]

could you try to avoid

btn.Attributes.add();

and write an onclick directly to the tag ... does the error persist in that case?
