不工作角剑道组合框占位符文本 [英] Angular-Kendo ComboBox placeholder text not working

问题描述

我有一个页面上一个简单的角剑道组合框没有最初选择的值。它应该显示的<一个href=\"http://docs.telerik.com/kendo-ui/api/web/combobox#configuration-placeholder\"><$c$c>placeholder文本在此情况下，而是它显示？未定义：未定义

I have a simple angular-kendo ComboBox on a page without an initially selected value. It should show the placeholder text in that case, but instead it's showing ? undefined:undefined ?

HTML

<select kendo-combo-box ng-model="Project" k-options='projectOptions'></select>

JS

app.controller('MyCtrl', function($scope) {    
  $scope.projectData = [
    {name: 'Bob', value: 1},
    {name: 'Tom', value: 2}
  ];

  $scope.projectOptions = {
    placeholder: "'Select...'",
    dataTextField: 'name',
    dataValueField: 'value',
    dataSource: {
      data: $scope.projectData
    }
  }
});

下面是一个 plunker 显示的问题。任何人都可以找出原因在哪里？

Here's a plunker that shows the problem. Can anyone spot the cause?

这在使用旧版本的角剑道的工作，但它不是在当前版本中工作。

This used to work in an older version of angular-kendo, but it's not working in the current version.

推荐答案

这是有点关系这个问题：<一href=\"https://github.com/angular/angular.js/issues/1019\">https://github.com/angular/angular.js/issues/1019

This is somewhat related to this issue: https://github.com/angular/angular.js/issues/1019

解决方法很简单：使用＆LT;输入＆GT; ，而不是＆LT;选择＆GT; 元素：

The solution is simple: use an <input> instead of a <select> element:

<input kendo-combo-box ng-model="Project" k-options='projectOptions'/>

app.controller('MyCtrl', function($scope) {
  $scope.projectData = [
    {name: 'Bob', value: 1},
    {name: 'Tom', value: 2}
  ];

  $scope.projectOptions = {
    placeholder: "'Select...'",
    dataTextField: 'name',
    dataValueField: 'value',
    dataSource: {
      data: $scope.projectData
    }
  }
});
