本文介绍了从元素中获取类名称,然后选择具有相同类的所有元素的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
$('.classToClick').live("click", function () {
$(this).attr('disabled', 'disabled');
$(this).val("lol");
$.post('post.php', {
string: "lalala"
}, function (data) {
$(this).removeAttr('disabled');
});
})
此代码不起作用,因为在后期我们使用$(this).当我们将其更改为.classToClick时,它将起作用.
This code doesn't work, because in post we use $(this). When we change it to .classToClick, it works.
如何获得元素的类单击,以便我们可以像这样使用它?
How can we get the class of the element clicked so that we could use it like this?
$('.classToClick').live("click", function () { var className = $(this).name; $(this).attr('disabled', 'disabled'); $(this).val("lol"); $.post('post.php', { string: "lalala" }, function (data) { $(className).removeAttr('disabled'); }); })是否可以做类似的事情?
Is it possible to do something similar?
推荐答案单击后,您需要捕获类名,可以通过以下方式完成:
Upon clicking, you will need to capture the class name, which can be done via:
var className = $(this).attr('class'); //Alternatively, $(this).prop('class'),当您稍后在$选择器中引用它时,需要包括句点以表示正在选择一个类,例如:
and when you later refer to it inside of the $ selector, you need to include the period to denote a class is being selected, as such:
$('.' + className).removeAttr('disabled');代码:
$('.classToClick').live("click", function() { var className = $(this).attr('class'); $(this).attr('disabled', 'disabled').val("lol"); $.post('post.php', {string : "lalala"}, function(data) { $('.' + className).removeAttr('disabled'); }); })工作示例
