0) Forget Javascript.
1) Go with jQuery which is better than Javascript.
2) If you don't believe, do Google search for "Javascript vs jQuery"
3) AngularJs is a javascript library like jQuery but it's also framework. Some people use Angular to create SPA.
Here a CP article. 10 Reasons Web Developers Should Learn Angular[^]
and one more post. 10 Reasons Why You Should Use AngularJS[^]

If you want to perform just client side operations, go with jQuery which is more than enough. And it'd be better to learn jQuery before start learning other javascript libraries like AngularJs, KnockOutJs, etc.,

jQuery IS javascript. Big Grin | :-D

But yes, it is an easier way to use JavaScript.

Advice like this will get me very confusing. First, JavaScript is a language. Second jQuery and AngularJS are libraries developed using JavaScript.

Agree with you. I just suggested OP to go with jQuery instead of javascript. Still there're many people fighting with old javascript code. Hereafter I'll add more details to avoid things like this. Thank you.

I suggest at least using the jQuery library but of course you'll want to design out your app first and make sure just the jQuery library can handle it properly.

For example, if you'll have grids then you'll likely want a separate library like jqGrid or something.

The point is your requirements and your current experience combined with your ability to learn new libraries should drive what you end up using.

I have been using AngularJS for about a month and have put it into a project and i really like it. AngularJS is written using javascript so javascript is something you SHOULD know. The nice thing about AngularJS is that you can incorporate javascript and jQuery (as long as you have a reference to it). When in doubt i use javascript over Jquery. Sure Jquery is easier to use but native javascript is much faster.

Hello there,

I want to have a function that turns this :

http://examplesite.com/folders/images/myphoto.jpg

to this :

http:\/\/examplesite.com\/folders\/images\/myphoto.jpg

Can any of you help me with that? I'm not that good at JS but I need this : /

Thanks.

If all that you want is to replace a '/' with '\/' then I would recommend you look into the String.replace method you get with javascript.

JavaScript

function repl(url) {
    return url.replace('/', '\/');
}

But since you mentioned you were trying to turn a URL into JSON I am thinking there is more to what you are asking. In which case I would recommend the following:

Validate and submit a form containing data and a file using ajax/jquery

XML

I have a form containing data and a file input fields,
I want to submit and validate this form using jquery and ajax through one script.

Below is my form:

    <form id="datas" method="post" enctype="multipart/form-data">
        <input type="text" name="firstName" value="" />
        <input name="pic" type="file" />
        <button>Submit</button>
    </form>

Now I have this code to validate the data

    $('#datas').validate({
        rules: {
            firstName:{
                required: true,
                minlength: 2,
                maxlength: 100
            }

        },
        messages: {
            firstName: {
                required: "Please Enter first name",
                minlength: jQuery.format("Enter at least {0} characters"),
                maxlength: jQuery.format("Enter atmost {0} characters"),
            }
        }
    });

Then I have a seperate code that could submit the form

    $("#datas").submit(function(){

        var formData = new FormData($(this)[0]);

        $.ajax({
            url: sucess.php,
            type: 'POST',
            data: formData,
            async: false,
            success: function (data) {
                alert(data)
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });


**QUESTION:**

Please how can I combine these two scripts to validate the file and data fields and also submit to the success page.

Since you are using the jQuery validation plugin why not read and follow their documentation where it appears they have some answers to questions similar.
