Answer 1

我为JQueryUI v1.10.2 - 2013-04-17制作了这段代码

HTML代码:

<select class="combobox" placeholder="123">
 <option>...</option>
 ...
</select>

JS代码:

$.widget( "ui.combobox", {
    _create: function() {
        this.wrapper = $( "<span>" )
            .addClass( "ui-combobox" )
            .insertAfter( this.element );

        this._createAutocomplete();
        this._createShowAllButton();
        this.input.attr("placeholder", this.element.attr('placeholder'));
    },
});

$(function() {
    $( ".combobox" ).combobox();
});

在输入中添加ID并在javascript中运行此代码

$("#yourID").attr("placeholder", "Your Text Here");
