KindEditor-新添加的字符串进行html标签删除

,
afterChange:function() {//创建编辑框之后
var self = this;
self.sync();
//对比是否有不同，有不同就开始，对
var htmlstr = self.text();
if(editor1Str.length!=htmlstr.length){
var strIndex = htmlstr.indexOf(editor1Str);
var newStr = "";
if(strIndex!=0&&strIndex!=-1){//前面有新文段
newStr = htmlstr.substr(0,htmlstr.length-editor1Str.length);
newStr = newStr.replace(/<[^>]+>/g, '');
editor1Str = newStr+editor1Str;
}
if(strIndex==0){//后面有新文段或者没有
newStr = htmlstr.substr(editor1Str.length,htmlstr.length-editor1Str.length);
newStr = newStr.replace(/<[^>]+>/g, '');
editor1Str = editor1Str+newStr;
}
}
