通过javascript或控制台选择全部复选框 [英] Select All checkbox by javascript or console

问题描述

我的网页上有100个复选框。为了测试目的，我想勾选所有这些框，但手动点击是耗时的。

I am having 100 Checkboxes on my webpage. For testing purposes I want to tick all those boxes, but manually clicking is time consuming. Is there a possible way to get them ticked?

可能是JavaScript或Chrome控制台窗口，什么？

Perhaps a JavaScript or Chrome Console window, anything?

推荐答案

最直接的方法是抓取所有的输入，只过滤复选框，并设置checked属性。

The most direct way would be to grab all your inputs, filter just the checkboxes out, and set the checked property.

var allInputs = document.getElementsByTagName("input");
for (var i = 0, max = allInputs.length; i < max; i++){
    if (allInputs[i].type === 'checkbox')
        allInputs[i].checked = true;
}

使用jQuery - 我不是说你应该开始只是勾选所有的复选框进行测试 - 你可以简单地做

If you happen to be using jQuery—and I'm not saying you should start just to tick all your checkboxes for testing—you could simply do

$("input[type='checkbox']").prop("checked", true);

或作为Fabricio指出：

or as Fabricio points out:

$(":checkbox").prop("checked", true);
