匹配url 添加为a标签

var reg = /(http:\/\/|https:\/\/)((\w|=|\?|\.|\/|&|-)+)/g;

if(str.indexOf(‘<a href=‘)==-1){  // 过滤下a标签

str= str.replace(reg, "<a href=‘$1$2‘>$1$2</a>");

}

2、文本换行处理

breakStr(str) {

var regBr = /(\r\n)|(\n)|(\?)/g;

str = str.toString().replace(regBr, "<br>");

var reg = /(http:\/\/|https:\/\/)((\w|=|\?|\.|\/|&|-)+)/g; 匹配Url

str = str.replace(reg, "<a href=‘$1$2‘ target=‘_blank‘>$1$2</a>");

return str;

},
