jQWidgets jqxPivotGrid itemsRenderer属性用法及代码示例

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。 jqxPivotGrid 是一个函数强大且轻量级的数据可视化小部件，完全用 JavaScript 语言编写。该小部件提供了许多高级函数，并且可以根据不同的需求进行高度定制。

itemsRenderer 属性用于设置或获取指定 jqxPivotGrid 小部件的 itemsRenderer 函数，该小部件用于渲染枢轴的行和列。该函数应该返回一个有效的 HTML 字符串。

用法:

用于设置项目渲染器属性：

$('Selector').jqxPivotGrid({itemsRenderer: function (Domain) {
    var BG_Color = "red";
    return "<div style='background: "
        + BG_Color
        + "; padding: 4px; width: 270px; height: 160px;'>"
        + Domain.text
        + "</div>";
});

为了得到项目渲染器属性：

$('#jqx_Pivot_Grid').jqxPivotGrid('itemsRenderer');
