    Hi Wei,

    First, you have to retrive the Array from your JSONModel using following method.

    var oArray = this.getView().getModel("modelName").getProperty("/rootStringValue");

    Then you have to loop through both array and JS object. In your case, the dataUser is already an Array.

    var i, name, obj, targetIndex;

    for (i=0; i < dataUser.length; i++) {

    obj = dataUser[i];

    for (name in obj) {

    if ( name == "user_name" && == "user_2")

    targetIndex = i;



    via this targetIndex, you can locate the right array element contains the information and you can retrieve what you want.

    var targetObj = dataUser[targetIndex];

    var id = targetIndex.user_id;

    I think this id is namely what you I want. My code is not optimized, but I think the logic is right. You can give it a try.

    Hi Wei,

    Depending on the control you are binding on, most likely you'll have to apply filtering.

    You can do this, on for example a table, using this following guide:

    What control are you trying to bind your data on?

    (You usually define your filters in the binding)
