按类名删除元素? [英] Removing elements by class name?

本文介绍了按类名删除元素?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

我有以下代码来查找带有类名的元素:

I have the below code to find elements with their class name:

// Get the element by their class name
var cur_columns = document.getElementsByClassName('column');

// Now remove them

for (var i = 0; i < cur_columns.length; i++) {

}

我只是不知道如何删除它们......我是否必须引用父母或其他东西?处理此问题的最佳方法是什么?

I just don't know how to remove them..... do I HAVE to reference the parent or something? What's the best way to handle this?

@ Karim79:

这是JS:

var col_wrapper = document.getElementById("columns").getElementsByTagName("div");
var len = col_wrapper.length;

alert(len);

for (var i = 0; i < len; i++) {
    if (col_wrapper[i].className.toLowerCase() == "column") {
        col_wrapper[i].parentNode.removeChild(col_wrapper[i]);
    }
}

这是HTML:

<div class="columns" id="columns">
    <div class="column"><input type="checkbox" name="col_list[]" value="cows">cows</div>
    <div class="column"><input type="checkbox" name="col_list[]" value="cows">cows</div>
    <div class="column"><input type="checkbox" name="col_list[]" value="cows">cows</div>
    <div class="column"><input type="checkbox" name="col_list[]" value="cows">cows</div>
    <div name="columnClear" class="contentClear" id="columnClear"></div>
</div>

编辑:最后只使用jQuery选项。

Well ended up just using the jQuery option.

推荐答案

使用jQuery(我认为你可以在这种情况下使用它),你可以这样做:

using jQuery (which you really could be using in this case, I think), you could do this like so:

$('.column').remove();

否则,您将需要使用每个元素的父元素将其删除:

Otherwise, you're going to need to use the parent of each element to remove it:

element.parentNode.removeChild(element);
