问题描述
我有一个表单,如果用户提交有错误的表单(如果页面会刷新),我需要存储所有单选按钮的状态。
<我希望实现与此类似的东西:
$(function(){
$('。示例输入[type =radio]:选中')。each(function(){
$(this).attr(checked,true);
});
非常感谢任何帮助!
解决方案
您可以将其状态存储在本地存储中,并在每次加载页面后将其恢复。
存储值的小例子:
$('#myCheckbox')。click(function(){
localStorage ['my.checkbox'] = this.checked;
});
恢复它:
$('#myCheckbox')。prop('checked',localStorage ['my.checkbox'] =='true');
i have a form on which i need to store the state of all radio buttons if a user submit the form with errors (which in case the page would refresh).
I want to achieve something quite similar to this:
$(function(){
$('.example input[type="radio"]:checked').each(function(){
$(this).attr("checked",true);
});
Any help would much be appreciated!
解决方案
You could store it's state within local storage and restore it after each page load.
Little example on storing the value:
$('#myCheckbox').click(function () {
localStorage['my.checkbox'] = this.checked;
});
Restore it:
$('#myCheckbox').prop('checked', localStorage['my.checkbox'] == 'true');
