点击按钮,生成一组一组combobox和slider时,避免控件Id相同,导致控件冲突的方法

前端之家收集整理的这篇文章主要介绍了点击按钮,生成一组一组combobox和slider时,避免控件Id相同,导致控件冲突的方法前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

如下效果图,点击一次添加按钮,动态生成一组comboBox和slider。由于easyUI的下拉框和滑块使用相同的控件id,通过JS生成控件,如果两个id一样就会造成冲突,例如点击第一组的下拉框,第二组的下拉框也会跟着动。

 

如何避免这个冲突?

思路:可以在板块div外层加一个id,区分每组策略的comboBox和slider。

步骤:

1、点击,用字符串拼接,插入HTML代码,这里的HTML代码有一个唯一Id

2、根据板块div的Id查找空间id,调用生成comboBox和slider

具体实现代码如下:

data1 ="id":0"text":"0:00""selected":"id":1"text":"01:00""id":2"text":"02:00""id":3"text":"03:00""id":4"text":"04:00""id":5"text":"05:00"</span><span style="color: #008000;"&gt;/*</span><span style="color: #008000;"&gt;第一个策略,<a href="/tag/shengcheng/" target="_blank" class="keywords">生成</a>时间下拉框、亮度音量滑块</span><span style="color: #008000;"&gt;*/</span><span style="color: #000000;"&gt;
