jQWidgets jqxToolBar addTool()方法

jQWidgets是一个JavaScript框架，用于为PC和移动设备制作基于Web的应用程序。它是一个非常强大的、优化的、与平台无关的、并被广泛支持的框架。jqxToolBar被用来说明一个jQuery widget，它显示一个可以自发附加各种工具的工具栏。此外，默认情况下，jqxToolBar支持一些小工具，即jqxButton、jqxToggleButton、jqxDropDownList、jqxComboBox以及jqxInput。然而，自定义的工具也可以被附加。

addTool()方法是用来添加一个工具到显示的jqxToolBar。它不返回任何东西。

语法:

$('#Selector').jqxToolBar('addTool', "button", "first", false, 
   function (type, tool, menuToolIninitialization) {
    var width = 90;
    if (menuToolIninitialization === true) {
        width = "100%";
    }
    tool.text("New_Button");
    tool.jqxButton({ width: width });
});

参数:

type。它是新工具的声明类型。其中，可能的值可以是按钮、下拉列表、toggleButton、组合框、输入以及自定义。它的类型是字符串。
Position。这是要插入工具的既定位置。这里可能的值是第一个和最后一个。它的类型是字符串。
Separator。它说明在新工具后面是否要包括一个分隔符。这里可能的值是true和false。它的类型是布尔值。
初始化回调函数。它是陈述的回调函数，在新工具被初始化后将被调用。它的类型是函数。在这里，可以传递三个参数，它们是：。
1. type。它是工具的既定类型。
2. tool。它是一个陈述的jQuery对象，代表工具。
3. menuToolInitialization。它说明回调函数是为工具栏工具调用的，即false，还是为弹出式菜单工具调用的，即true。它的类型是布尔值。
