How can I “click” all divs in the firebug console?

Question

How can I perform a "click" action on all the rows that start with "user_" in the following html:

<div id="rows">
  <div id="user_1"></div>
  <div id="user_2"></div>
  <div id="user_3"></div>
  <div id="user_4"></div>
</div>

Answer 1

jQuery('div[id^="user_"]').click();

Answer 2

假设“执行单击操作”是指“触发单击事件”，则可以使用属性starts-with选择器，以及不带参数的click方法（等同于trigger("click") ）：

$("div[id^='user_']").click();

Answer 3

$("div[id^=user_]")​​​​​​​​​​​​​​.click();

You can paste that inside the Firebug console or just put it in your page as it is valid JavaScript either way.

Answer 4

Selecting all elements with an attribute starting with some string:

$('div[id^="user_"]')

"Clicking" them:

$('div[id^="user_"]').click();

However, you might want to add a class to them, which beats string matching on attributes.
