使用jQuery，如何更改元素的html值? (div) [英] Using jQuery, how do I change the elements html value? (div)

问题描述

使用ajax请求，我想更改div的内容.

Using a ajax request I want to change content of my div.

<div id="d1">202</div>

所以我想将内容更改为其他数字.

So I want to change the content to a different number.

$('d1').InnerText???

另外，说我想增加这个数字，我该怎么做?我必须转换为int吗?

Also, say I wanted to increment the number, how could I do that? Do I have to convert to int?

推荐答案

$("#di").html('My New Text');

查看 jQuery文档.

如果您想增加数字，可以这样做

If you wanted to increment the number, you would do

var theint = parseInt($("#di").html(),10)
theint++;
$("#di").html(theint);

P.S.不知道它是否是错字，但是您需要在选择器中包括#，以使jQuery知道您正在寻找ID为di的元素.也许，如果您来自原型，就不会期望到这个，只是让您知道.

P.S. Not sure if it was a typo or not, but you need to include the # in your selector to let jQuery know you are looking for an element with an ID of di. Maybe if you come from prototype you do not expect this, just letting you know.
