html转义代码，v-html 显示原始html字符串

methods: 
 htmlEscape(str) {       let s = "";       if (str.length == 0) return "";       s = str.replace(/&/g, "&amp;");       s = s.replace(/</g, "&lt;");       s = s.replace(/>/g, "&gt;");       s = s.replace(/ /g, "&nbsp;");       s = s.replace(/\'/g, "&#39;");       s = s.replace(/\"/g, "&quot;");       return s;     }


调用： let htmlStr = "<a href='http://www.baidu.com'>前往百度</a>" this.htmlEscape(htmlStr )
