Det du skickar är inte ett JSON objekt, debugar jquery så få du ett error när den försöker köra parse JSON
edit:
Important: As of jQuery 1.4, if the JSON file contains a syntax error, the request will usually fail silently. Avoid frequent hand-editing of JSON data for this reason. JSON is a data-interchange format with syntax rules that are stricter than those of JavaScript's object literal notation. For example, all strings represented in JSON, whether they are properties or values, must be enclosed in double-quotes. For details on the JSON format, see http://json.org/.
alla propertys måste ha " runt sig och inte bara vara tom:
[{"optionValue":10, "optionDisplay": 10}, {"optionValue":20, "optionDisplay": 20}, {"optionValue":30, "optionDisplay": 30}, {"optionValue":40, "optionDisplay": 40}, {"optionValue":50, "optionDisplay": 50}, {"optionValue":60, "optionDisplay": 60}, {"optionValue":70, "optionDisplay": 70}, {"optionValue":80, "optionDisplay": 80}, {"optionValue":90, "optionDisplay": 90}, {"optionValue":100, "optionDisplay": 100}]
skriv om:
$("#fldAmount").html(options);
$('#fldAmount option:first').attr('selected', 'selected');
dock, onödigt att hämta #fldAmont 2 ggr räcker att du hämta den en gång:
$("#fldAmount").html(options).filter("option:first").attr("selected",true);
