<input type='text' value='1' />
<input type='text' value='2' />

方案1: 没问题
$("input").combobox({

}).combobox("setValues", ['1','2','3']);

方案2: 会报错
$("input").combobox({
xxx
});

$("input").combobox("setValues", ['1','2','3']);

Firefox 提示: TypeError: $.data(...) is undefined

方案2里感觉 combobox 控件还没有初始化完毕, 这是为什么?

EasyUI object must be initialized before the method call

问题的原因就是调用 setValues 时, easyui 还没有初始化完毕.
但是为什么呢? 上面不是调用了 $("input").combobox({ }) 吗?

it is your jQ selector 's problem.

Code:

var before=$('input');
console.log("before init:",before.length);
before.combobox({});

var after=$("input");
console.log("after init:"after.length);

//error!!!!
after.combobox("setValues", ['1','2','3']);

you will see in Console:

Code:

before init:1
after init:3

easyui generate other 2 input elements.

定义combobox 但实际还没有渲染正确地应该在定义时的onloadsuccess事件中赋初值
例
$("input").combobox({
onloadsuccess:function(){
$(this).combobox('setValue', xxx)
}
});
