javascript serialize checkbox value
I have a form in this project that i am serializing so that i can pass it to PHP and make some database calls开发者_如何学C based on input values. everything was working fine until I added a checkbox to my form and tried to serialize it.
<input type="checkbox" name="reduceHolOT" id="reduceHolOT" checked="checked" ></input>
how can i get the checked or value attribute of this checkbox into a
$('form').serialize()
along with other data in my form?
You shoud add a value attribute for your checkbox. Good practice you know.
But serialize should be putting the string "reduceHolOT=on" into the result if the checkbox is checked. If it isn't checked, nothing will show up whether you have a value or not.
Maybe you should try this:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>serialize demo</title>
<style>
body, select {
font-size: 12px;
}
form {
margin: 5px;
}
p {
color: red;
margin: 5px;
font-size: 14px;
}
b {
color: blue;
}
</style>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<form>
<select name="single">
<option>Single</option>
<option>Single2</option>
</select>
<br>
<select name="multiple" multiple="multiple">
<option selected="selected">Multiple</option>
<option>Multiple2</option>
<option selected="selected">Multiple3</option>
</select>
<br>
<input type="checkbox" name="check" value="check1" id="ch1">
<label for="ch1">check1</label>
<input type="checkbox" name="check" value="check2" checked="checked" id="ch2">
<label for="ch2">check2</label>
<br>
<input type="radio" name="radio" value="radio1" checked="checked" id="r1">
<label for="r1">radio1</label>
<input type="radio" name="radio" value="radio2" id="r2">
<label for="r2">radio2</label>
</form>
<p><tt id="results"></tt></p>
<script>
function showValues() {
var str = $( "form" ).serialize();
$( "#results" ).text( str );
}
$( "input[type='checkbox'], input[type='radio']" ).on( "click", showValues );
$( "select" ).on( "change", showValues );
showValues();
</script>
</body>
</html>
