Can'；我想不出是什么'；JavaScript中的if语句有问题[更新9月1日-我的for循环运行了两次，如何修复？]

var MarkUpChecker=（函数iffe（）{
"严格使用",；
变量URL={
“foo”：http://foo.com',
“酒吧”：http://bar.com',
"baz":"http://baz.com',
‘耶’：’http://www.yay.com',
“废话”：http://www.blargh.com'
},
publicAPI；
函数getURL（）{
for（var i=0；i})();已编辑

将id添加到锚点
并尝试使用
jQuery
更改
标记
目标属性：

<a id="custom_target" href="http://foo.com/path/to_page.aspx"> 
    <img src="img/some_image.jpg">
</a>

if (link.href.indexOf(url) !== -1) {
    $('#custom_target').attr('target', '_self');
}
else{
    $('#custom_target').attr('target', '_blank');
}

代码中存在多个问题，包括逻辑问题。比如说

function getURL() {
    for (var i = 0; i < arguments.length; i++) {
        return URLS[arguments[i]];//always returns arguments[0]
    }
}

函数getURL（）{
for（var i=0；i

我重写它的方式是，它接受并返回数组（参见下面的JSFIDLE）。

下一期

  //root problem. this for loop See solution in JSFiffle
  for (var i = 0, len = arguments.length; i < len; i++) { // Using a for loop to allow unlimited arguments to be passed in
    url = getURL(arguments[i]); // We are calling the publicApi.getURL() method and passing the looped argument from above

    //and rewrite target again and again. I remove outer loop
    for (var j = 0, jlen = avon_rep_container_links.length; j < jlen; j++) { // This loop goes over the whole documents links...
      link = avon_rep_container_links[j];
      if (link.href.indexOf(url) !== -1) { //...and we are checking each argument passed in to see if it matches the object value stored in the getURL function e.g. like a switch statement..
        parser = document.createElement('a'); //...if so we are essentially adding a blank tag to all the documents in the document
        parser.href = link.href;//parser isn't used 

        link.setAttribute('target', '_self');//will be changed in the next loop
        newPathName = parser.pathname;


        if (newPathName.search(/Executive|District|Division|National/) != -1) { // Added check for these strings for SMO page
          newPathName = newPathName.split('/').pop();
          newstr = newPathName;

        } else {
          newstr = newPathName;
        }
        link.href = newstr;
      } else {
        link.setAttribute('target', '_blank');

      }
    }

//根本问题。此for循环请参见JSFiffle中的解决方案
for（var i=0，len=arguments.length；i
