Javascript RegEx partial match

Question

I have a regular expression pattern, which validates for a three digit number

/^\\d{3}$/.test(\"123\")   // true
/^\\d{3}$/.test(\"123.\")  // false
<         


        

Answer 1

You would be better off by using a library like maskedinput.js. You can then setup your text input like follows:

jQuery(function($){
    $("#your_input").mask("999");
});

UPDATE

you can use a validator for forms and preset specific types of fields to validate
