jQWidgets jqxToolBar addTool()用法及代码示例


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、优化、独立于平台且得到广泛支持的框架。 jqxToolBar 用于说明一个 jQuery 小部件,该小部件显示可以自发附加各种工具的工具栏。此外,默认情况下,jqxToolBar 支持一些小部件,即 jqxButton、jqxToggleButton、jqxDropDownList、jqxComboBox 以及 jqxInput。但是,也可以附加自定义工具。

addTool()方法用于向显示的jqxToolBar添加工具。它不返回任何内容。

用法:

$('#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:这是新工具的指定类型。其中,可能的值可以是按钮、下拉列表、切换按钮、组合框、输入以及自定义。它是字符串类型。
  • Position:这是工具要插入的规定位置。这里可能的值是第一个和最后一个。它是字符串类型。
  • Separator:它指出新工具后是否要包含分隔符。这里可能的值是 true 和 false。它是布尔类型。
  • 初始化回调函数:这是新工具初始化后要调用的指定回调函数。它是函数类型。这里可以传递三个参数,如下:
    1. type:这是该工具的指定类型。
    2. tool:它是一个代表该工具的声明 jQuery 对象。
    3. menuToolIninitialization:它指出是否为工具栏工具调用回调函数(即 false)或弹出菜单工具(即 true)。它是布尔类型。
