迭代一个json响应字符串？

Question

How can i iterate my json string return from a Java file in JavaScript ?

My JSON string having the following hierarchy;

ResponseObject -> SId -> SeId -> QId-> List of data . I need to access that list of data by looping through it using JavaScript.

Answer 1

You can use jQuery to parse JSON String or alternatively, you can create a JSON Object using the javascript eval() function.

Once you have a JSON object created, you can use dot notation to traverse your json, like

var value = ResponseObject.SId.SeId.Qid;

Where the attributes from the dot notation are your JSON key in the json string.

Answer 2

Use this notation: myobjet["MyAttributeName"].

for( var SId in ResponseObject ) {

    for(var SeId in ResponseObject[SId] ) {

        for(var QId in ResponseObject[SId][SeId] ) {
            var value = ResponseObject[SId][SeId][QId];
        }

    }

}

I didn't test it, but it should work.
