在javascript数组中隐藏元素

问题描述

var question= dataQuestions;

我正在加载数组集合"dataQuestions".

下一个Iam在"0th"位置添加另一个项目，如下所示

I am loading "dataQuestions" which is an array collection.

next Iam adding another item at "0th" position as following

question.splice(0,0,{"Qid": 0,"Answer":null,"Text":""}

现在我

Now i am

function insertData(sQ, question) {
			sQ.kendoDropDownList({
				dataTextField : "Text",
				dataValueField : "Qid",
				dataSource : question
                           
			});
		} 

所以现在我的下拉列表中包含一些问题，例如"wht is ....?".但是在"0th"位置将有一个空行.
我希望该rowrow隐藏或不可点击.(基于我对下拉列表中任何问题的点击，某些功能会发生).

So now my dropdown contains few questions like "wht is....?".But at "0th" position there will be an empty row.
I want that emptyrow to hide or non clickable.(based on my click on any question in the dropdown some functionality happens).

Any help?

推荐答案

<select>
  <option>Volvo</option>
  <option>Saab</option>
  <option disabled="disabled">Mercedes</option>
  <option>Audi</option>
</select>

但我不知道您是否可以将此属性传递给kendoui下拉列表:(

But I don''t know if you can pass this property to the kendoui dropdown :(
