JS function called from JSP works fine in FireFox won't work in IE

[Trish Hartnett]

Hello,

I was wondering if anybody could suggest anything please.

I have a JavaScript function :
function checkNullability(fieldName, actualFieldName){
var ruleName= fieldName+"Nullable";
var ruleNameNullable = evXl(ruleName);
var value = actualFieldName.value;
if (ruleNameNullable=="false" && (value==null || value==""))
{
alert("This is a mandatory field. Please enter something");
actualFieldName.focus();
}
}

and it's being called from JSP. this function works fine in Firefox but won't work in IE. Apologies for having to change write evXl here. I can't write evXl with an "a" replacing the X due to security controls.

I've been told that by a colleague that the problem might be because the name being passed to the checkNullability form is like:
name="staticDataItemList[3].value"
in the outputted HTML code.

The value of the actualFieldName is set in the JSP as:
lt html:text name="staticDataItemList" property="value" size="50" indexed="true"
onclXck= "setActualFieldName('name')"
/gt

Sorry for the unreadable code. I can't post this topic with the word onclXck (where i= X ) in it due to security controls on the JavaRanch website.

Can anybody suggest anything please ?

Thanks in advance,
Trish.

I really hate to see that usage - its a sign of confusion. JSP is writing an HTML page that contains (you trust) some JavaScript. JSP is NOT calling anything, it is writing plain text that the browser is supposed to interpret.

Now, with that distinction clearly in mind, do a view source in the browser and see what has actually been written. Your JS will probably have to be modified to let it cope with both IE and Firefox.

Trish, your code will be more readable if you use the UBB code tags to preserve its formatting. You can include the word onclick by substituting the HTML entity o for the 'o' in onclick.

And, as William pointed out, the fact that an HTML/Javascript page was generated by a JSP is moot, so I've moved this off to the HTML forum for you.

Mozilla and Firefox have a JavaScript console on it. Look at it, it gives you an error message that should tell you what your issue is.

Hello,

thank you for replying. The JavaScript console in FireFox shows no errors. Same with the one in IE. It's almost as if IE can't has problems recognising fieldnames that have full stops in them.

Thanks in advance for any suggestions at all,
Trish.

Whoops, I switch browsers when I posted that. I thought you said it dod not work in Firefox...

It is a lot better to change this:

var ruleName= fieldName+"Nullable";
var ruleNameNullable = eval(ruleName);
var value = actualFieldName.value;

to something like this:

var ruleName= fieldName+"Nullable";
var ruleNameNullable = document.forms[0].elements[ruleName];
var value = document.forms[0].elements[actualFieldName].value;

Thank you for replying, but I don't think that the problem is with the eval.
I tried writing a small function to store the fieldName as it appears in the form:

function setFormFieldName(actualFieldNameInForm){
actualFieldName = actualFieldNameInForm;
alert("field name as it appears in HTML: " +actualFieldName );
}

The alert works in FireFox but not in IE. The fieldName is staticDataItemList[3].value

I'm sorry. I know shouldn't hedge bets by posting on more than one website at one time.

I post on 12 different places daily, I really do not care. Just do not feel like talking in 2.
