The recent week to do a page, the process of production encountered a variety of problems, from which I can see the JS Foundation is not solid enough, ANGULARJS is just the level of entry, now will be the production process encountered in a summary, convenient for later review.

One, string type and JSON convert each other

var json = ' {' name ': ' liSi ', ' Password ': ' 321 '} '; String Type

var jsonarr = ' [{' name ': ' Zhangsan ', ' password ': ' 123 '},{' name ': ' liSi ', ' Password ': ' 321 '}] '; String Type

When you see such data, to get the value of name, password, the first thought must be, Json.password, Jsonarr[0].name, Jsonarr[1].name, But the actual print will be undefined
