javascript - JSON parsing not working in jQuery -


i have text field id search_json on form contains:

{"standard_id":"2","attribute1":["","stan"],"attribute2":[""],"attribute3":["","air force"],"attribute4":["","bob"],"selected_index":3} 

upon event, call button click, want to:

1) read in json , parse object:

search_json = $.parsejson($("#search_json").val()) 

2) remove "attribute1" object

delete search_json["attribute1"] 

3) write json out text field:

$("#search_json").val(json.stringify(search_json)) 

i'm kind of surprised it's not working, though. delete call nothing. matter of fact,

search_json.hasownproperty("attribute1") 

returns false. , yet can log object console , indeed object values. going wrong here?

update: actually,

search_json.hasownproperty("attribute1") 

does work. but, if attribute name text field, so:

attribute_name = $("#attribute_name").attr("id") 

and:

console.log attribute_name 

shows "attribute1", not work:

search_json.hasownproperty(attribute_name) 

returns false. mystifying.

i don't it. i'm using fiddle code , correct

http://jsfiddle.net/ddqbe/1/

the final object is:

attribute2: array[1] attribute3: array[2] attribute4: array[2] selected_index: 3 standard_id: "2" 

attribute1 delete correclty
