getItemByValue Issue

[marchipMember]

Hi

i have a drop down list. I add two item.

var currentSeriesString =”A|B”;

var source = currentSeriesString.split(‘|’);

$(“#series”).jqxDropDownList({ source: source, checkboxes: true, width: 200, height: 25, theme: ‘classic’ });

 

When i Call

var item = $(“#series”).jqxDropDownList(‘getItemByValue’, “B”);

 

item is undefined. Why?

Thanks

Hi marchip,

getItemByValue works for items with label and value when the displayMember and valueMember properties are specified. The source in your sample is a simple array and there is no value there.

var source = new Array();
var arr = currentSeriesString.split(‘|’);
for (i = 0; i < arr.length; i++) {
var itm = {};
itm["name"] = arr[i];
source.push(itm);
}

$("#series").jqxDropDownList({ source: source, displayMember: 'name', valueMember: 'name', checkboxes: true, width: 200, height: 25, theme: 'classic' });

Not function.

Hi marchip,

Below is a working code:

                var currentSeriesString ="A|B";
                var source = new Array();
                var arr = currentSeriesString.split('|');
                for (i = 0; i < arr.length; i++) {
                    var itm = {};
                    itm["name"] = arr[i];
                    source.push(itm);
                }
                var dataObj = { localdata: source };
                var dataAdapter = new $.jqx.dataAdapter(dataObj);
                $("#series").jqxDropDownList({ source: dataAdapter, displayMember: 'name', valueMember: 'name', width: 200, height: 25, theme: 'classic' });
                var item = $("#series").jqxDropDownList('getItemByValue', 'B');
