There are a number of validation plugins available, after some searching I think I found the plugin you're using based on the usage here.
I created a fiddle to demo how to make a field required and numeric ... click here for fiddle.
Based on the code you provided, it looks like you're only including the base validate.js
library. You need to be sure to include the css
file, and if you want to use some out of the box validations, such as number validations then you will also need to include the additional-methods.js
file. All these files can be found HERE.
Here is the code from the fiddle above..
<form id="myform">
<input type="text" class="box" id="box" name="box">
<br/>
<input id="submit" type="submit" value="Validate!">
</form>
$(document).ready(function()
{
$("#myform" ).validate(
{
rules:
{
box:
{
required: true,
number: true
}
}
});
});
