绑定 itemDataSource 来选择 html 元素? [英] Bind itemDataSource to select html element?

问题描述

是否可以将List-Binding绑定到HTML Select()元素上，将绑定的内容显示为元素?

Is it possible to bind a List-Binding to a HTML Select () element to display the contents of the binding as elements?

我现在正在使用它，但似乎不起作用:

Im using this right now, which doesn't seem to work:

<select data-win-options="{itemDataSource: ...)}"></select>

推荐答案

有一种没有声明式绑定的编程方式:

There is a programmatical way without declarative binding:

JavaScript 部分:

JavaScript part:

// Load data
var options = [
    { optionValue: 1, optionText: 'One', selected: false },
    { optionValue: 2, optionText: 'Two', selected: true },
    { optionValue: 3, optionText: 'Three', selected: false }
];

// Fill select box
options.forEach(function (value, i) {
    var newOption = document.createElement("option");
    newOption.text = value.optionText;
    newOption.value = value.optionValue;
    if (value.selected) {
        newOption.selected = true;
    }
    myBox.add(newOption);
});

HTML 部分:

<select id="myBox"></select>

否则，您可以使用带有模板的 WinJS.UI.ListView:http://msdn.microsoft.com/en-us/library/windows/apps/br211837.aspx

Otherwise, you can use a WinJS.UI.ListView with a template: http://msdn.microsoft.com/en-us/library/windows/apps/br211837.aspx
