如何使用Javascript删除Firefox的enter-key

Question

如何使用Javascript将Firefox的enter-key删除为下图？

我在我的代码中添加了更多"("和")",它在IE中运行得很好,但它似乎在Firefox或Chrome浏览器中不起作用.

另外,请告诉我IE和Firefox之间的区别对我的代码有影响.

这是我的代码:

Javasript:

// Extract the labels by adding "(" and ")"
labels[i] = txt1 + "(" + txt + ")";
...
var str = document.getElementById("demo").innerHTML;
alert(str);
var res = str.replace(/(<br>)/g, '');
alert(res);

Answer 1

我想你想要删除换行符.

做这个:

// Extract the labels by adding "(" and ")"
labels[i] = txt1 + "(" + txt + ")";
...
var str = document.getElementById("demo").innerHTML;
alert(str);
var res = str.replace(/\n/g, '');
alert(res);

\n 用于匹配换行符.
