替换jQuery字符串中的文本(Replacing text in a jQuery string)

替换jQuery字符串中的文本(Replacing text in a jQuery string)

我想用图像替换jQuery字符串中的一些文本，例如：

//original string str = "This is a message from peter to john"; //After replacement str = "This is a message from <img src='peter.jpg'> to <img src='john.jpg'>";

在PHP中它可以这样做：

$string = strtr($str, array('peter'=>'<img src="peter.jpg" />', 'john'=>'<img src="john.jpg" />'));

请问有没有类似的方法来做到这一点在jQuery中就像php方法一样。 或者更好的想法来实现这一目标？

I want to replace some text in a jQuery string with images for example :

//original string str = "This is a message from peter to john"; //After replacement str = "This is a message from <img src='peter.jpg'> to <img src='john.jpg'>";

In php it can be done like this:

$string = strtr($str, array('peter'=>'<img src="peter.jpg" />', 'john'=>'<img src="john.jpg" />'));

Please is there a similar way to do this in jQuery just like the php method. Or any better idea to achieve this?

最满意答案

使用replace()方法

var str = "This is a message from peter to john";
str = str.replace(/\b(?:peter|john)\b/g, "<img src='$&.jpg'>");
console.log(str) 
  
 
Use replace() method 
 
 
 
  
  
var str = "This is a message from peter to john";
str = str.replace(/\b(?:peter|john)\b/g, "<img src='$&.jpg'>");
console.log(str)
