javascript - Send form data using ajax

Question

I want to send all input in a form with ajax .I have a form like this.

<form action="target.php" method="post" >
    <input type="text" name="lname" />
    <input type="text" name="fname" />
    <input type="buttom" name ="send" onclick="return f(this.form ,this.form.fname ,this.form.lname) " >
</form>

And in .js file we have following code :

function f (form ,fname ,lname ){
    att=form.attr("action") ;
    $.post(att ,{fname : fname , lname :lname}).done(function(data){
        alert(data);
    });
    return true;

But this is not working.i don't want to use Form data .

Answer 1

as far as we want to send all the form input fields which have name attribute, you can do this for all forms, regardless of the field names:

First Solution

function submitForm(form){
    var url = form.attr("action");
    var formData = {};
    $(form).find("input[name]").each(function (index, node) {
        formData[node.name] = node.value;
    });
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}

Second Solution: in this solution you can create an array of input values:

function submitForm(form){
    var url = form.attr("action");
    var formData = $(form).serializeArray();
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}
