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
Javascript Solutions
Solution 1 - Javascript
You can use a serialize() function of JQuery:
var datastring = $("#preview_form").serialize();
$.ajax({
type: "POST",
url: "your url.php",
data: datastring,
success: function(data) {
alert('Data send');
}
});
And read in PHP:
echo $_POST['datastring']['dialog_box_textarea_1'];
echo $_POST['datastring']['radiobutton_1'];
........
And get data-* to tag HTML5 you can see this example:
<div id="texto" data-author="Ricardo Miranda" data-date="2012-06-21">
<h4>Lorem ipsum</h4>
<p>
Lorem ipsum dolor sit amet, ius integre eligendi et,
sea ut expetendis conclusionemque,
mel at ornatus invenire. His ad moderatius definiebas omittantur,
liber saepe albucius sea cu.
Audire tamquam dolores vis ne, mediocrem consulatu eum ex.
Duo te agam saepe convenire, et fugit iisque his.
</p>
<script type="text/javascript">
$(function() {
alert("The text is write " + $('#texto').data('author'));
});
And
<div id="texto" data-author='{"nombre":"Ricardo","apellido":"Miranda"}' data-date="2012-06-21">
...
</div>
<script type="text/javascript">
$(function() {
alert("The text is write " + $('#texto').data('author').apellido + ", " +
('#texto').data('author').nombre);
});
</script>
Solution 2 - Javascript
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("&");
}
Solution 3 - Javascript
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
Solution 4 - Javascript
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);
Solution 5 - Javascript
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);
Solution 6 - Javascript
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);
Solution 7 - Javascript
If you want to use $(formName).serializeArray() or $(formName).serialize(),
you must add name='inputName' on your input element. or will not work!
Solution 8 - Javascript
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;
}), {});
Solution 9 - Javascript
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;
};
