我在组合框中使用 jquery,我无法在界面中显示组合框。firebug 中的错误如下:
类型错误:$ 未定义:$.widget("ui.combobox", {
我正在使用以下文件 jquery.ui.combobox.js:
代码 :
$.widget("ui.combobox", {
options: {
openDialogButtonText: "+",
dialogHeaderText: "Add option",
saveButtonImgUrl: null,
closeButtontext: "Ok"
},
_create: function() {
var selectBox = $(this.element),
id = selectBox.attr("id"),
self = this;
selectBox.addClass("ui-combobox");
// create HTML to inject in the DOM
this.addHtml(id, selectBox);
// turn dialog html into a JQuery UI dialog component
this.addDialog(id);
// @todo set proper button height (roughly equal to select height)
$("#" + id + "-button-opendialog").bind("click", function() {
$("#" + id + "-editor-dialog").dialog("open");
}).button();
$("#" + id + "-button-save").bind("click", function() {
self.addOption(id, selectBox);
}).button();
this._init();
return this;
},
addHtml: function(id, selectBox) {
var imgHtml = "";
if (this.options.saveButtonImgUrl != null) {
imgHtml = '<img src="' + this.options.saveButtonImgUrl + '" alt="opslaan" />';
}
$(' <button id="' + id + '-button-opendialog">' +
this.options.openDialogButtonText +
'</button>' +
'<div id="' + id + '-editor-dialog" class="ui-combobox-editor">' +
'<input id="' + id + '-newitem" type="text" /> ' +
' <button id="' + id + '-button-save">' +
imgHtml + ' Opslaan' +
' </button>' +
'</div>').insertAfter(selectBox);
},
addDialog: function(id) {
var options = this.options;
$("#" + id + "-editor-dialog").dialog( {
autoOpen: false,
modal: true,
overlay: {
opacity:0.5,
background:"black"
},
buttons: {
// @todo make button text configurable
"Ok": function() {
$("#" + id + "-editor-dialog").dialog("close");
return;
}
},
title: options.dialogHeaderText,
hide: 'fold'
});
},
addOption: function(id, selectBox) {
var newItem = $("#" + id + "-newitem");
// @todo do not allow duplicates
if (newItem !== null && $(newItem).val().length > 0) {
// @todo iterate over options and get the highest int value
//var newValue = selectBox.children("option").length + 1;
var highestInt = 0;
selectBox.children("option").each(function(i, n) {
var cInt = parseInt($(n).val());
if (cInt > highestInt) {
highestInt = cInt;
}
});
var newValue = highestInt + 1;
var newLabel = $(newItem).val();
selectBox.prepend("<option value='" + newValue + "' selected='selected'>" + newLabel + "</option>");
this._trigger("addoption", {}, newValue);
// cleanup and close dialog
$(newItem).val("");
$("#" + id + "-editor-dialog").dialog("close");
} else {
this._trigger("addoptionerror", {}, "You are required to supply a text");
}
},
_init: function() {
// called each time .statusbar(etc.) is called
},
destroy: function() {
$.Widget.prototype.destroy.apply(this, arguments); // default destroy
// $(".ui-combobox-button").remove();
// $(".ui-combobox-editor").remove();
}
});
你能帮我么?
