Question

I need to do some ugly stuff. But I cannot do it another way. what I need is

<a href='some/url/?with&params' onclick="(if confirm('Do you wanna submit?')
    {some code to submit form in href property})">  

but I don’t know how to make inline script work… and I hesitate about the way of submitting it with window.location or document.location. Any ideas?

Answer 1

Try this:

on html:

<a href='some/url/?with&params' onclick="if (confirm('Do you wanna submit?')) return MyValidation.actionSubmit();">Submit</a>

<script type="text/javascript" src="myValidation.js" />

myValidation.js

I used json and javascript closures on this answer.

; //starts with this to close other js not yet closed
var MyValidation = {

    actionSubmit : function() {

            //your code go here

            //example of calling another function
            MyValidation.anotherFunction();

            //example of accessing a global variable (for your validation)
            MyValidation.variable;

            //example of declaring local variable
            var word = "hello";

            //example of calling another function with parameters
            MyValidation.anotherFunctionWithParameters(word, MyValidation.variable);

            //the returning
            return MyValidation.someValidation(word);
    }

    //Yes, this is a comma. 
    //I'm putting in the beginning so we see this and didn't forget :)
    ,anotherFunction : function() {

            //some code
            //maybe a return
    }

    ,variable : {}

    ,anotherFunctionWithParameters : function(param1, param2) {

            //more code, maybe a return
    }

    ,someValidation : function(parameter) {
        //some validation
        return true|false;
    }

};

Take a look on this:
