javascript - Jquery 不会在表单中更新

Question

我制作了以下代码来替换页面中我无法编辑但只能操作的表单字段。但是，代码什么也不做。在 chrome 控制台中，当我打印一个变量时它工作正常。代码如下：

//GET val from drop DROP DOWN
var office_id = FieldIDs["OfficeName"];//Gets the input id
var offices;//gets the value from the drop down
$("#FIELD_"+office_id).change(function(){
    offices = $(this).val();
}).change();
//The below gets the id's of all the input fields
var address_id = FieldIDs["Address"];
var address2_id = FieldIDs["Address2"];
var city_id = FieldIDs["City"];
var state_id = FieldIDs["State"];
var zip_id = FieldIDs["Zip"];
var phone_4id = FieldIDs["Number4"];//phone
var phone_id = FieldIDs["Number1"];//fax
var pdfm4 = FieldIDs["pdfm4"];
var pdfm = FieldIDs["pdfm"];
if(offices == "SoCal Accounting"){
    $('#FIELD_'+address_id).val("7421 Orangewood Avenue");
    $('#FIELD_'+address2_id).val("");
    $('#FIELD_'+city_id).val("Garden Grove");
    $('#FIELD_'+state_id).val("CA");
    $('#FIELD_'+zip_id).val("92841");
    $('#FIELD_'+phone_4id).val("+1 714.901.5800");//phone
    $('#FIELD_'+phone_id).val("+1 714.901.5811");//fax
}
