Passing formname in the javascript function.

[jenis23]

Hi,
I have one jsp page in which i am using dynamicform to create the forms.. I have 2 forms. I want to pass the formname to one javascript function and using that name i want to use the methods provided by that form.

<code>
isc.DynamicForm.create({
ID: "temp",width: 300,height: 100,backgroundColor:"white",
fields: [{ wrapTitle:false,name: "Id",width: "*",formItemType: "staticText", title: "userid",type: "text",
}]
});

</code>

i am passing this formname using this function ..
<code>
dochange('temp');
</code>


javascriptfile.js

<code>
dochange(){
fname=arguments[0];

uid=fname.getValue("id");
alert(uid);
}
</code>

i am not able to get the output .. it throws javascript exception that it doesn t support the method or property ...

Note that in your dochange() method you are receiving a string holding the name of a form. Then you try to use this string as if it is a form instance. An easy change is to pass the form instance by removing the quotes from 'temp' which then references the global form object named temp.

You get something like:

dochange(temp);

dochange(form) {
    uid = form.getValue("id");
    alert(uid);
}

or you can eval() the string name to reference the form instance from name (not recommended):

dochange('temp');

dochange(){
    fname=arguments[0];

    uid= eval(fname + ".getValue('id');");
    alert(uid);
}

Another option I believe will work is that each form is registered by its ID as global in the window[] object. So,

dochange('temp');

dochange(){
    fname=arguments[0];

    uid= window[fname].getValue("id");
    alert(uid);
}

Be sure to match the parameter to getValue with the exact name used in defining the field (id vs Id).

A good book on JavaScript might be in order.
