近期有用的代码

//ISBN编号正则匹配
let reg = /^(?:\d+-){4}\d+$|^\d{13}$/;

//替换所有的中文逗号
 let str =str.replace(/，/ig, ',');

//句子中指定词组高亮显示
    if(phrase.length && sentence){
      phrase.slice(0, 4).map(item => {
        let reg = new RegExp("(" + item + ")", "g");
        let str = document.querySelector(".pm_modal_sentence").innerHTML;  
        let newstr = str.replace(reg, "<font color=#FEA313>$1</font>");
        document.querySelector(".pm_modal_sentence").innerHTML = newstr;   
      })
    }
