Question

好的，这是我的问题：我有一个谷歌分析代码，如下所示：

<script type="text/javascript">
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
_gaq.push(['_trackPageview']);
(function() {
    var ga = document.createElement('script');
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(ga, s);
})();
</script>

我想替换这一行：

ga.src = ('https:' == document.location.protocol ? 'https://' : 'http:/') + '.google-analytics.com/ga.js'

这一行：

ga.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'stats.g.doubleclick.net/dc.js'

但是我无法编辑原始代码，我只能添加它。有没有办法创建一个以某种方式查找和替换此行的代码？

请帮忙，

如何将修改后的脚本置于当前脚本之上，然后重新压缩现有脚本？像这样：

<script type="text/javascript">
    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
    _gaq.push(['_trackPageview']);
    (function() {
        var ga = document.createElement('script');
        ga.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'stats.g.doubleclick.net/dc.js';
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ga, s);
    })();
</script>
<script type='application/x-suppress'>
<script type="text/javascript">
    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
    _gaq.push(['_trackPageview']);
    (function() {
        var ga = document.createElement('script');
        ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ga, s);
    })();
</script>

这个怎么样：

<script type="text/javascript">
    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
    _gaq.push(['_trackPageview']);
    (function() {
        var ga = document.createElement('script');
        ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ga, s);
    })();
</script>
<script type="text/javascript">
    document.getElementsByTagName('script')[0].remove();
    document.getElementsByTagName('script')[0].remove();
    var _gaq = [];
    _gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
    _gaq.push(['_trackPageview']);
    (function() {
        var ga = document.createElement('script');
        ga.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'stats.g.doubleclick.net/dc.js'
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ga, s);
    })();
</script>

另一个不要求你注意脚本索引的选项如下（注意新脚本有一个id）：

<script type="text/javascript">
    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
    _gaq.push(['_trackPageview']);
    (function() {
        var ga = document.createElement('script');
        ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ga, s);
    })();
</script>
<script id="scriptFixer" type="text/javascript">
    var scripts = document.getElementsByTagName('script');
    var scriptCount = scripts.length;
    var regex = new RegExp('.google-analytics.com/ga.js');
    for (var i = scriptCount - 1; i >= 0; i--) {
        var script = scripts[i];
        if (script.id !== 'scriptFixer' && (script.innerHTML.match(regex) !== null || script.src.match(regex) !== null)) {
            script.remove();
        }
    }
    var _gaq = [];
    _gaq.push(['_setAccount', 'UA-xxxxxxx-x']);
    _gaq.push(['_trackPageview']);
    (function() {
        var ga = document.createElement('script');
        ga.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'stats.g.doubleclick.net/dc.js'
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ga, s);
    })();
</script>

查找和替换Javascript，更改链接，是否可能？
