Calling a function from within a value attribute

[K Riaz]

How do I call a function within the 'value' attribute of an input tag?

e.g.

<input type="text" value="'return myValue()'"/>

This doesn't seem to work. The myValue() function returns a string which should be the input's value. How can it be done?

You can't do it that way. Rather, put something like the following into an onload handler:

 
document.myForm.elementName.value = myValue();

U could also call the javascript function onclick of a button(if u have one on the screen)and populate the value of ur text element in the javascript function.

dnyan ginde, JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "u" instead of spelling out "you" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.

I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.
