本文介绍了删除子节点(或元素)或设置innerHTML =“”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

当清除诸如选择框,表或列表之类的HTML元素时,删除节点是否更好/更快(例如, select.options.remove(i) table.deleteRow(i))或只是清空innerHTML(例如, select.innerHTML =)?或者是否重要?



一个例子是重新初始化一个表。特定的选择字段的值应为后续的HTML表加载不同的值。当选择值发生变化时,表格需要重新初始化。

解决方案

我做了一个没有坏的新测试。 / p>



由于部分样本设置是测试的一部分,因此这可能会使结果偏斜,这并不完美。 >

这使得 innerHTML 更快,但我不知道多少。


When clearing HTML elements such as select boxes, tables, or lists, is it better/faster to remove the nodes (e.g., select.options.remove(i), table.deleteRow(i)) or just empty the innerHTML (e.g., select.innerHTML = "")? Or does it matter?

An example case would be reinitializing a table. A specific select field's value should load different values for a subsequent HTML table. When the select value changes, the table needs to be reinitialized.

解决方案

I made a new test that isn't broken.

It's not perfect either since part of the sample setup is part of the test so this might skew the results.

This gives that innerHTML is faster but I don't know by how much.
