请教一个正则:
数据有时候是这样:
["二s","李s","王s","一s"]
[{"DEVID":1,"Area":"广州","USERID":null,"USERNAME":"王s","DEVTYPE":null,"DevName":"iPad2","DevIMEI":"IPAD2346523985687","IsUsable":1,"BindDate":"2013-05-13T09:05:33","UPDATEUSER":null,"UPDATETIME":"0001-01-01T00:00:00"}]
或者
["二s","李s","王s","一s"]
或者
[{"DEVID":1,"Area":"广州","USERID":null,"USERNAME":"王s","DEVTYPE":null,"DevName":"iPad2","DevIMEI":"IPAD2346523985687","IsUsable":1,"BindDate":"2013-05-13T09:05:33","UPDATEUSER":null,"UPDATETIME":"0001-01-01T00:00:00"}]
在代码中如何判断这种字符中是否包含 ][ 呢?
success: function (returnValue) { //select var returnJson = returnValue.split('][')[0] + ']'; var returnValue1 = '[' + returnValue.split('][')[1];
indexOf() 方法
你那不就是 json 吗?干嘛要字符串截取?
你那不就是 json 吗?干嘛要字符串截取?
["二s","李s","王s","一s"]这段要单独拿出 放在下拉框中
[{"DEVID":1,"Area":"广州","USERID":null,"USERNAME":"王s","DEVTYPE":null,"DevName":"iPad2","DevIMEI":"IPAD2346523985687","IsUsable":1,"BindDate":"2013-05-13T09:05:33","UPDATEUSER":null,"UPDATETIME":"0001-01-01T00:00:00"}]
这段要形成表格
有时候是有2段数据,有时候只有后面一段数据。所以我想判断一下是否有2段数据。该怎么写呢?
indexOf() 方法
var str="Hello world!"//值大于0,有2段数据,则截取。否则就是一段数据,直接赋值不截取。是这个意思吗?if(returnValue.indexOf("][") > 0) { var returnJson = returnValue.split('][')[0] + ']'; var returnValue1 = '[' + returnValue.split('][')[1];...}else{ var returnValue;}
indexOf() 方法
//我这样测试了一下,var returnValue = "[1][2]"的时候是可以,但是var returnValue = "[1]";的时候就不行,该怎么做呢?
