JS工具类(持续更新)

1.判断密码级别:

function checkPwd(str) { var Lv = 0; if (str.length < 6) { return Lv } if (/[0-9]/.test(str)) { Lv++ } if (/[a-z]/.test(str)) { Lv++ } if (/[A-Z]/.test(str)) { Lv++ } if (/[\.|-|_]/.test(str)) { Lv++ } console.error(Lv) return Lv; }; checkPwd('_qasda123sdwe');

2.模板字符串还能这么用: 字符串拼接!

let url = "hello${name}+${age}"; var test = function (url, data) { const keys = Object.keys(data); const dataList = keys.map(function (key) { return data[key] }); return new Function(keys.join(','), 'return `' + url + '`') .apply(null, dataList); } console.log(test(url, {id: "10", name: "aaa", age: "100"}))
