setAttribute使属性名称为小写 [英] setAttribute makes the attribute name lowercase

问题描述

我使用 var l = document.createElement（label）; 创建元素，并使用 l.setAttribute（分配其属性formControlName， E）; 。
问题是setAttribute方法将formControlName放在小写字母中，如下图所示。我使用离子，所以需要大写字母。有谁看到我做错了什么？

I create elements with the var l = document.createElement("label"); and I assign its attributes with l.setAttribute("formControlName","e");. The problem is that the setAttribute method puts the formControlName in lowercase letters as you can see in the image below. I work with ionic so the capital letters are needed. Does anyone see what I did wrong?

推荐答案

请改用：

l.setAttributeNS(null, "formControlName","e");

'setAttributeNS（）'不会将名称转换为小写。

'setAttributeNS()' doesn't convert the name to lower case.
