javascript - jQuery 替换为变量不起作用

Question

我正在尝试用 data.replace 替换字符串，如果使用硬代码或静态值，它工作正常。但现在我想用循环替换多个值，但它不起作用。

我的代码:

for(var i = 0; i<words.length; i++){
    var r = words[i];
    data = data.replace(/\[(\[qid:{r})\]]/g, words[i]);
}

单词包含:

Array [ "hid_1", "hid_2", "hid_6", "hid_7" ]

我的数据是:

Site: [[qid:hid_1]]<br>

Block: [[qid:hid_2]]<br>

Nimewo kay la: [[qid:hid_6]]<br>

Latitude: [[qid:hid_7]]

它是 HTML 内容。

我在这里只需要变量:

for(var i = 0; i<words.length; i++){

        var r = words[i];
        data = data.replace(/\[(\[qid:hid_1)\]]/g, 'test');
               //data.replace(/\[(\[qid:{r})\]]/g, 'test');

    }

Answer 1

var words = [ "hid_1", "hid_2", "hid_6", "hid_7" ];

var data = "Site: [[qid:hid_1]]<br>\
Block: [[qid:hid_2]]<br>\
Nimewo kay la: [[qid:hid_6]]<br>\
Latitude: [[qid:hid_7]]";

for(var i = 0; i<words.length; i++){
        var r = words[i];
        var reg = new RegExp('\\[\\[qid:' + r +'\\]\\]');
        data = data.replace(reg, r);
}
