Question

我对JS非常陌生并拥有我正在尝试调整的代码。当我添加阵列的时候，我只用了几个项目来测试它并且它工作正常，现在它只是不起作用，我无法弄清楚它有什么问题！

基本上，我正在尝试使用网页上的图片更改卡片类型的每个实例

以下是代码：

    window.onload = function(){
 var cardname = new Array();
 cardname[0] = "Ace of Hearts^<img src='http://upload.wikimedia.org/wikipedia/commons/thumb/7/7c/Ornamental_h_a.svg/88px-Ornamental_h_a.svg.png' />";
 cardname[1] = "2 of Hearts^<img src='http://upload.wikimedia.org/wikipedia/commons/thumb/7/7c/Ornamental_h_2.svg/88px-Ornamental_h_2.svg.png' />";

  repl = part[1];

  while (page.indexOf(findit) >=0){
   var j = page.indexOf(findit);

任何帮助都将被理解为什么这个代码不起作用！

Answer 1

我测试时代码正常工作。它失败的一个可能原因是你有一些其他代码正在替换你设置的load事件，例如通过在body标签中设置onload属性。

替换整个正文内容可能与操纵内容的其他代码冲突。您最好只更换体内特定元素的内容。

我宁愿使用正则表达式来进行单个替换，而不是循环遍历字符串并一次进行一次替换。如果您替换特定元素中的内容而不是整个主体，这应该会有很大帮助。

大多数图片代码都是相同的，因此您不必为每张卡片重复这一点。图像应具有符合标准的alt属性，您可以使用原始文本。

window.onload = function(){
  var cardname = {

要替换特定元素的内容，您可以使用：

var elements = document.getElementsByTagName('DIV');
for (var i=0; i<elements.length; i++) {
  elements[i].innerHTML = elements[i].innerHTML.replace( ...same as above... );
}

由于标签只包含卡片名称，您根本不需要更换，您只需获取名称并将图像放在其中：

var elements = document.getElementsByTagName('LI');
for (var i=0; i<elements.length; i++) {
  if (elements[i].className && elements[i].className == 'card') {
    var name = elements[i].innerHTML;
    var img = cardname[name];
    if (typeof(img) == "undefined") {
      img = "8/89/Back07.svg/88px-Back07";
    }
    elements[i].innerHTML = '<img src="http://upload.wikimedia.org/wikipedia/commons/thumb/'+img+'.svg.png" alt="'+name+'" />';
  }
}
