javascript - 如何替换js中的文本？

Question

假设我有以下内容:

var s = "This is a test of the battle system."

我有一个数组:

var array = [
"is <b>a test</b>",
"of the <div style=\"color:red\">battle</div> system"
]

是否有一些函数或方法可以使我可以处理字符串 s 使得输出为:

var p = "This is <b>a test</b> of the <div style=\"color:red\">battle</div> system."

基于数组中的任意元素？

注意数组元素要按顺序执行。因此，查看数组 1 中的第一个元素，找到字符串“s”中“替换”的正确位置。然后查看数组元素 2，在字符串“s”中找到“替换”的正确位置。

请注意，该字符串可以包含数字、括号和其他字符，例如破折号(虽然没有 <>)

更新:在 Colin DeClue 的评论之后，我认为你想做一些与我原先想象的不同的事情。

这里是你如何做到这一点

//your array
var array = [
    "is <b>a test</b>",
    "of the <div style=\"color:red\">battle</div> system"
];
//create a sample span element, this is to use the built in ability to get texts for tags
var cElem = document.createElement("span");

//create a clean version of the array, without the HTML, map might need to be shimmed for older browsers with a for loop;
var cleanArray = array.map(function(elem){
   cElem.innerHTML =  elem;
   return cElem.textContent;
});
//the string you want to replace on
var s = "This is a test of the battle system."

//for each element in the array, look for elements that are the same as in the clean array, and replace them with the HTML versions
for(var i=0;i<array.length;i++){
  var idx;//an index to start from, to avoid infinite loops, see discussion with 6502 for more information
  while((idx = s.indexOf(cleanArray[i],idx)) > -1){
    s = s.replace(cleanArray[i],array[i]);
    idx +=(array[i].length - cleanArray[i].length) +1;//update the index
  }
}
//write result 
document.write(s);

原始答案，以防这毕竟是你的意思

是的。使用join

var s = array.join(" ");

Here is a working example in codepen
