如何在JavaScript中实现多维数组

Question

I have called a service through ajax and got a list of values and i have parsed the values as js object in below line

   var parseviewpresctiption = $.parseJSON(viewprescription);

i have an array of 20 values as json object which has value in each object.but the value in different object belong to single question id.So i need to group the value and based on the id and store it in multi dimensional array.in my above code i have declared a multi dimensional array but i could not able to store the value in array and it is throwing the error.

   var questions = {};
   for(var i=0 ; i<3 ; i++){
   questions[questionId][i] = {
                'questionId' : parseviewpresctiption[prop].option.optionId,
                'column' : parseviewpresctiption[prop].option.content,
                'row' : parseviewpresctiption[prop].question.content,
                'value' : parseviewpresctiption[prop].text,
                'table' : tableTypeName,
                'answerId' : parseviewpresctiption[prop].answerId
                          }
             };

If i remove the multi dimensional array like

           questions[questionId][i] = {
                'questionId' : parseviewpresctiption[prop].option.optionId,
                'column' : parseviewpresctiption[prop].option.content,
                'row' : parseviewpresctiption[prop].question.content,
                'value' : parseviewpresctiption[prop].text,
                'table' : tableTypeName,
                'answerId' : parseviewpresctiption[prop].answerId
                          }

the last value with that id is getting stored in the array.How to declare a multi dimensional array and group the values based on the id

i need to get the value and append the value in single table row

Sample data Object answerId : 968 doctor : null option : Object content : "N/A" optionId : 8 proto : Object patient : Object numVisits : 0 patientId : 66 rdoUser : Object vipScore : 0 proto : Object question : Object content : "Personal Physician Last Name" help : null option : null question : null questionId : 43 questionType : "TXT" proto : Object questionnaireTemplate : Object description : "Current Medical Problems" name : "MEDICAL_HISTORY" questionnaireTemplateId : 12 rdoUser : Object shared : false proto : Object sequenceNumber : null text : "S"

Answer 1

Use forEach method, You should check this link here .

Can you just console.log response and drop the screenshot here, It's hard to figure out from the data sample you've posted.

Answer 2

You can use array map method instead.

var questions = parseviewpresctiption.map(function(v) {
                    return {
                      questionId : v.option.optionId,
                      column : v.option.content,
                      row : v.question.content,
                      value: v.text,
                      table : tableTypeName, //I'm assuming that you
                      answerId: v.answerId
                    };
                });

This will return array of objects. Sorry for the late reply mate!
