</html>

Here the code which will get all form field values:

 $("#hidAll").append($("#preview_form :input").map(function () {
     if ($(this).val() != 'Submit') {
         if ($(this).is('select')) {
             var aa = $(this).children('option').map(function () {
                 return $(this).val();
             }).get().join("|");
             return $(this).attr('name') + '|' + aa;
         } else if ($(this).is('input:checkbox')) {
             return $(this).attr('name').substring(0, $(this).attr('name').length - 2) + '|' + $(this).val();
         } else {
             return $(this).attr('name') + '|' + $(this).val();
         }
     }
 }).get().join(","));
 alert($("#hidAll").html());

From this I am getting the output value as follows:

textfield_1|dgdfg,
checkboxgroup_1|Option 1,
checkboxgroup_1|Option 2,
checkboxgroup_1|Option 3,
radiobutton_1|Option 1,
radiobutton_1|Option 2,
radiobutton_1|Option 3,
dropdown_1|Option 1!Option 2!Option 3

I want the out as following:

textfield_1|dgdfg,
checkboxgroup_1|Option 1!Option 2!Option 3,
radiobutton_1|Option 1!Option 2!Option 3,
dropdown_1|Option 1!Option 2!Option 3

This question is related to javascript html jquery

The answer is


jQuery has very helpful function called serialize.

Demo: http://jsfiddle.net/55xnJ/2/

//Just type:
$("#preview_form").serialize();

//to get result:
single=Single&multiple=Multiple&multiple=Multiple3&check=check2&radio=radio1

I know you're using jQuery but for those who want a pure Javascript solution:

// Serialize form fields as URI argument/HTTP POST data
function serializeForm(form) {
    var kvpairs = [];
    for ( var i = 0; i < form.elements.length; i++ ) {
        var e = form.elements[i];
        if(!e.name || !e.value) continue; // Shortcut, may not be suitable for values = 0 (considered as false)
        switch (e.type) {
            case 'text':
            case 'textarea':
            case 'password':
            case 'hidden':
                kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            case 'radio':
            case 'checkbox':
                if (e.checked) kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            /*  To be implemented if needed:
            case 'select-one':
                ... document.forms[x].elements[y].options[0].selected ...
                break;
            case 'select-multiple':
                for (z = 0; z < document.forms[x].elements[y].options.length; z++) {
                    ... document.forms[x].elements[y].options[z].selected ...
                } */
                break;
        }
    }
    return kvpairs.join("&");
}

If you want to use $(formName).serializeArray() or $(formName).serialize(), you must add name='inputName' on your input element. or will not work!


I needed to get the form data as some sort of object. I used this:

$('#preview_form').serializeArray().reduce((function(acc, val) {
  acc[val.name.replace('[', '_').replace(']', '')] = val.value;
  return acc;
}), {});

Add this on to the end of it:

var array = $("#hidAll").html();

x = array.split(',');
key=s="";
for (i=0; i<x.length; i++) {
  oldkey = key;
  key = x[i].split('|')[0];
  if (oldkey==key) s+='!';
  else s+=',\n'+key+'|';
  s+=x[i].split('|')[1];
}
s = s.substring(1);
$('#hidAll').html(a);

Try this for getting form input text value to JavaScript object...

var fieldPair = {};
$("#form :input").each(function() {
    if($(this).attr("name").length > 0) {
        fieldPair[$(this).attr("name")] = $(this).val();
    }
});

console.log(fieldPair);

if you want get all values from form in simple array you may be do something like this.

function getValues(form) {
    var listvalues = new Array();
    var datastring = $("#" + form).serializeArray();
    var data = "{";
    for (var x = 0; x < datastring.length; x++) {
        if (data == "{") {
            data += "\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
        else {
            data += ",\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
    }
    data += "}";
    data = JSON.parse(data);
    listvalues.push(data);
    return listvalues;
};

The answer already been accepted, I just write a short technique for the same purpose.

var fieldPair = '';
$(":input").each(function(){
fieldPair += $(this).attr("name") + ':' + $(this).val() + ';';
});

console.log(fieldPair);
