Can anyone help me with this, I can't find a script on the internet that does this in jQuery. I need to remember the last state of drop down menu so that on page load the drop down option is already selected. The cookie expiration date should be 90 days or let me specify in the script. Since I already use jQuery on my page I want this cookie script to use jquery, jquery cookie plugin. Thank you in advance. I'm not a programmer, but I try.
<body onLoad="GETcookie()">
<select onChange="SETcookie()">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
推荐答案
您的代码看起来会像这样：
Your code would look a little something like this:
//checks if the cookie has been set
if($.cookie('remember_select') != null) {
// set the option to selected that corresponds to what the cookie is set to
$('.select_class option[value="' + $.cookie('remember_select') + '"]').attr('selected', 'selected');
}
// when a new option is selected this is triggered
$('.select_class').change(function() {
// new cookie is set when the option is changed
$.cookie('remember_select', $('.select_class option:selected').val(), { expires: 90, path: '/'});
});
这里是你选择 ：
<select class="select_class">
<option value="1">Row 1</option>
<option value="2">Row 2</option>
<option value="3">Row 3</option>
</select>
