What is the best method for looping through a JSON object string?

Here is the JsonResult I received:

[{"name":"Group 1"},{"name":"Group 2"},{"name":"Group 3"}]

I'm a little confused about how to iterate over this data or retrieve the values of the name inside the buildSelect function within the editoptions in jqGrid. Below is the code snippet from my colModel in jqGrid:

 { name: 'GroupName', index: 'GroupName', width: 60, align: 'center', search: false, editable: true, edittype: 'select',
   editoptions: {
                 dataUrl: "/Category/GetCategoryGroup",
                 buildSelect: function (response) {
                                  if (response && response.length) {
                                        // Use a for loop to access the name values           
                                  }                                                 
                            }                                          
                 } 
 },

Answer №1

let teams = [{"title":"Team A"},{"title":"Team B"},{"title":"Team C"}];
for(let i = 0; i< teams.length; i++) {
 let title = teams[i].title;
}

Answer №2

Similar to working with an array 

var myOb = [{"name":"Group 1"},{"name":"Group 2"},{"name":"Group 3"}] ; 

for (var i=0; i < myOb.length; i++) { 
 console.log(myOb[i]);
 console.log(myOb[i].name);
 console.log(myOb[i]['name']);
}

You can also iterate further for editing options

Answer №3

 if (response && response.length) {
    var options='<select>';
    for(var x=0; x< response.length; x++){
        var entry = response[x];
        var name = entry.name;
        options+="<option>"+name+"</option>";
    }
   options+="</select>";
   document.getElementById("dropdownArea").innerHTML = options; 
}

To display the dropdown, add a div like this:

<div id="dropdownArea"></div>

I hope this solution works for you.

Answer №4

A different method for looping through the array

let teams = [{"teamName":"Team A"},{"teamName":"Team B"},{"teamName":"Team C"}]; 

$.each( teams, function() {
    console.log(this.teamName);
});
