我给你做了例子。经过测试 - 工作正常。
你需要jQuery
图书馆
首先这里是表格:
<form id="my_form">
<input id="formText" type="text" name="formText" />
<br />
<label><input id="formCheck" type="checkbox" name="formCheck" /> check 1</label>
<br />
<label><input id="formCheck2" type="checkbox" name="formCheck2" /> check 2</label>
<br />
<textarea name="formTextarea" id="formTextarea" cols="20" rows="3"></textarea>
<br />
<label><strong>Time unit</strong>:</label>
<p>
<label><input type="radio" name="dataView" value="week" checked="checked" /> Week</label>
<label><input type="radio" name="dataView" value="month" /> Month</label>
<label><input type="radio" name="dataView" value="year" /> Year</label>
</p>
<input type="button" value="Serialize" onclick="serializeForm()" />
<input type="button" value="Unserialize" onclick="restoreForm()" />
</form>
单击按钮后,在js中调用相应的函数
这里是js:
序列化数据存储在formData
变量中,如果需要,您可以将其存储在cookie中,在数据库中等......然后根据您的要求加载它
<script type="text/javascript">
var formData;
function serializeForm() {
formData = $('#my_form').serialize();
}
function restoreForm() {
var obj = unserializeFormData(formData);
// Restore items one by one
if(obj.hasOwnProperty('formTextarea')) {
$('#formTextarea').val(obj.formTextarea);
}
if(obj.hasOwnProperty('formText')) {
$('#formText').val(obj.formText);
}
// Radio buttons
if(obj.hasOwnProperty('dataView'))
$('input[value="'+obj.dataView+'"]').attr('checked', true);
// Restore all checkbox. You can also iterate all text fields and textareas together, because the have same principle for getting and setting values by jQuery
$('#my_form input[type="checkbox"]').each(function(){
var checkName = $(this).attr('name');
var isChecked = false;
if(obj.hasOwnProperty(checkName))
isChecked = true;
$(this).attr('checked',isChecked);
});
}
function unserializeFormData(data) {
var objs = [], temp;
var temps = data.split('&');
for(var i = 0; i < temps.length; i++){
temp = temps[i].split('=');
objs.push(temp[0]);
objs[temp[0]] = temp[1];
}
return objs;
}
</script>
