Three functions commonly used when processing HTML text_html/css_WEB-ITnose

Today I talked with a friend about strengthening regular training for front-end engineers. So I will share three functions that are most commonly used when filtering HTML text. These functions are processed using regular expressions.

/* * 去掉HTML标签 */function stripHTML(oldString) {    return oldString.replace(/<\/?[^>]+>/gi, "");}/* * 去掉<br> */function stripBR(oldString) {    return oldString.replace(/<br.{0,}?>/gi, "");}/* * 去掉全角空格和半角空格 */function stripSpace(string) {    var tempstr;    tempstr = string.replace(/(^\s+)|(\s+$)/g, "");    tempstr = tempstr.replace(/(^　+)|(　+$)/g, "");    return tempstr;}
