对于任何类型的值采用双not ,可以得到其真正的boolean类型值 . 写法: if(!!cont){} [注: 有值就表示true , 没值或为false或为0就返回false]
null 与 undefined 是相等的 if(null == undefined) { 返回true } , [注: 非全等号由感叹号加两个等号(!==)表示,只有在无需类型转换运算数不相等的情况下,才返回 true。]
start : i = 5; 可以以这样的方式给语句加个标签, 方面下面调用.
js中文转码: encodeURI(encodeURI( //需要转码的内容 ))
要想实现点击下拉框, 选中内容在文本框中显示, 并且支持多选 , 请百度搜索 multiple-select
使用这种函数 var formData=$(“form”).serialize(); ,可以获取form表单中的参数和值, 以 name=2&pass=3的 形式连接到一块
