相等的值不相等吗？

Question

I'm having a really weird equality problem here. I cannot for life find out what's wrong - it's extremely odd.

I have this function:

function escapeAll(t) {
    var res = "";
    for(var i = 0; i < t.length; i++) {
        res += "\\" + t[i];
    }
    return res;
}

Now, why is this false ?

escapeAll(":D")==="\:\D"

Any ideas please? It's really driving me mad.

Answer 1

escapeAll(":D")==="\\:\\D"

这返回true ;）
