核心程式碼
<script>
String.prototype.html = function(encode) {
var replace =["'","'",""",'"'," "," ",">",">","<","<","¥","¥","&","&"];
var replaceReverse = ["&","'"];
var target;
if (encode) {
target = replaceReverse;
} else {
target = replace;
}
for (var i=0,str=this;i< target.length;i+= 2) {
str=str.replace(new RegExp(target[i],'g'),target[i+1]);
}
return str;
};
console.log("<div>我們</div>".html(true));
</script>效果圖
其中for迴圈大家可以看下用法
for (var i=0,str=this;i< target.length;i+= 2) {
str=str.replace(new RegExp(target[i],target[i+1]);
}
這個用法確實不錯，有get了一個新技能。
