How to pass parameter in javascript function

Question

I want to pass one parameter to a function called ForPaste().

My function is given below:

 var regex = /^[A-Za-z0-9ĀĒĪŌŪāēīōū\.\-\~\`\'' ]*$/;
 var SalaryRegex = /^[A-Za-z0-9,円\.\/\$ ]*$/;
 $.fn.ForPaste = function () {
 return this.each(function () {
 $(this).bind('input propertychange', function () {
 var value = $(this).val();
 if (!regex.test(value)) {
 $(this).val("");
 }
 });
 });
 };

This function is in a common JS file. It is called on individual pages. I want to test the regex depending on the parameter passed. So can I know the method about to call the ForPaste() function with the parameter.e.g $("#Text1").Forpaste('FromForm1'); and I get this FromForm1 in the ForPaste() function.

Answer 1

You define a formal parameter for your function.

 // formal parameter--v
$.fn.ForPaste = function (the_value) {
 alert( the_value ); // displays the argument passed
 // rest of your code
};

Whatever value was passed to ForPaste() will be referenced by the_value. (Of course you can change the name to any valid identifier.)

Answer 2

not sure what you are trying to do, because the answer seems so obvious. Will this do?

$.fn.ForPaste = function (theName) {
 if (theName.test(//)){
 return this.each(function () {
 ....
 });
 }
 return false
};

you can access the parameters by looking at arguments which isn't an array, but seems to be one. from within the function you can do an var theName=arguments[0] to get the value of the first parameter
