javascript - how to read Extjs dropdown value -



javascript - how to read Extjs dropdown value -

i've written listener on button action adds dynamic drop-down dialog —

name : './groupinfo' + count, id : 'groupinfo' + count, xtype : 'selection', type : 'select', emptytext:'select group...', options : '/bin/groupinfo/options.json', fieldlabel : 'group', width:200

options.json sends info in next pattern —

[{"text":"value1","value":"val1"}, {"text":"value2","value":"val2"}, {"text":"value3","value":"val3"}]

and drop-down values showing properly. want read selected value in js file, value coming out undefined. i've tried:

var dropdownval = document.getelementbyid("groupinfo"+i).value;

now, have tried gives me blank value when select —

var value1 = $('#groupinfo'+i+' option:selected').text(); alert(value1); var value2 = $('#groupinfo'+i).val(); alert(value2);

when tried value dynamically created text-box can value using getelementbyid not working dynamically created drop-down. please advise!
