Question

我有以下代码输出一个组合框：

<html>
<head>
// Included JS library
</head>
<body>
<script>
$(document).ready(function () 
{                
    var moduleAutoSuggest = getModuleAutoSuggestOption();

    // Create a jqxComboBox
    $("#jqxWidget").jqxComboBox(
    { 
        source: moduleAutoSuggest,
         placeHolder            : "text ...",
        width: '250', 
        height: '25px',
        disabled : false,
        searchMode: 'containsignorecase',
        autoComplete: true
    });

    obj = '';
      $('#jqxWidget').on('select', function (event) 
      {
                var args = event.args;
                if (args != undefined) {
                    var item = event.args.item;
                    if (item != null) 
                    {
                        obj = item;
                        printSelectedValue(obj);
                    }
                }
    });
});

function getModuleAutoSuggestOption()
{
    var moduleAutoSuggestOption = 
        [
            {"id" : "ALL_ICONS", "label":"All Icons"},
            {"id" : "ALL_LOGOS", "label":"All Logos"},
            {"id" : "ARTICLE", "label":"Newest Article"},
            {"id" : "ARTICLE_SUMMARY", "label":"Headlines For 10 Newest Articles"}
    ];

    return moduleAutoSuggestOption;
}   
</script>

<div id='content'></div>
        <div id='jqxWidget'>
        </div>

</body>
</html>

它给了我一个工作组合框，问题是， placeHolder 属性不起作用，如果我点击输入文本，选中的值不会更清晰

任何帮助都将得到应用

使用您的代码，我创建了一个似乎与jqwidgets示例fiddle完全相同的工作示例。你想要改变这个功能吗？

＆＃13;

$(function () 
{                
    var moduleAutoSuggest = getModuleAutoSuggestOption();

    // Create a jqxComboBox
    $("#jqxWidget").jqxComboBox({ 
        source: moduleAutoSuggest,
        placeHolder: "text ...",
        width: '250', 
        height: '25px',
        disabled: false,
        searchMode: 'containsignorecase',
        autoComplete: true
    });

    obj = '';
    $('#jqxWidget').on('select', function (event){
      var args = event.args;
      if (args != undefined) {
        var item = event.args.item;
        if (item != null) 
        {
          obj = item;
          printSelectedValue(obj);
        }
      }
    });
});

function getModuleAutoSuggestOption()
{
    return [
            {"id" : "ALL_ICONS", "label":"All Icons"},
            {"id" : "ALL_LOGOS", "label":"All Logos"},
            {"id" : "ARTICLE", "label":"Newest Article"},
            {"id" : "ARTICLE_SUMMARY", "label":"Headlines For 10 Newest Articles"}
    ];

}
