jquery, unselect checkbox
now i get value if i selected checkbox(id which was selected), but how get value when i unselected (id which was unselected)?
For example I push on 1, and i get value 1. When I unselect 1, i get value 1. I hope you understand my problem.
<script>
$(document).ready(function()
{
$("input[type=checkbox]").change(function(event){
$("#result").html("&id=" + this.value);
});
});
</script>
</head>
<body>
<input type="checkbox" name="checkbox_pref" value = "1"/>1
<input type="checkbox" name="checkbox_开发者_如何学Pythonpref" value = "2"/>2
<input type="checkbox" name="checkbox_pref" value = "3"/>3
<div id="result">result ...</div>
I simply create an array with all the checked values.
Then i can use join to create string out of it for later use.
$(document).ready(function() {
var $inputs = $("input[type=checkbox]");
$inputs.change(function(event){
var list = [];
$inputs.filter(':checked').each(function() {
list.push($(this).val());
});
$("#result").html("&id=" + list.join(",")); // Produces: &id = 1,2,3 (If they were all checked)
});
});
I believe if you use this.attr('checked') you should get back a boolean.
or you could do
this.is(':checked')
