How can I use these JavaScript math functions ?
For example, I want to compute the square of all <input> values in a form, without submiting the form.
Can you give a little example? Thank you.
You can act on each individual input using an each()(docs) loop.
Click here to test a working example. (jsFiddle)
$('a.square').click(function() {
$('#myform :text').each(function() {
this.value *= this.value;
});
});
$('a.square_root').click(function() {
$('#myform :text').each(function() {
this.value = Math.sqrt(this.value);
});
});
When either link is clicked, it finds all the text inputs in myform and iterates over them.
Inside the each function, this refers to the current input element.
