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能够处理字符串s,使输出为:

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？

请注意,数组元素应按顺序执行.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,找到字符串"s"中"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,如破折号(没有<>但是)

更新:在Colin DeClue发表评论之后,我想你想做一些与我原先想象的不同的事情.

以下是如何实现这一目标的方法

//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,如果这是你的意思毕竟

是.运用join

var s = array.join(" ");

这是codepen中的一个工作示例
