带有网格刷新的jqgrid多选过滤器问题 [英] jqgrid multiselect filter issue with grid refresh

问题描述

我正在检查演示以在我的系统中实施多选过滤项目.

I was checking the demo to implement Multiselect filtering in my project.

这确实是一个不错的演示，但存在一些问题. 选择一个过滤器，然后单击刷新按钮，然后过滤器不会重置.然后它将开始发生故障.

It is a nice demo indeed but has some issues with it. Select a filter and hit the refresh button then filters are not resetting. And after that it will starts malfunctioning.

过滤器未重置

有空的网格.

如何解决这些问题?任何的想法.

How can I fix these issues? Any Idea.

推荐答案

感谢您的错误报告！ 代码行.稍后，我会将该错误报告给trirand.

Thank you for the bug report! There are a bug in clearToolbar in the lines of the code. I will report the bug later to trirand.

要解决此问题，必须使用filterToolbar的beforeClear回调:

To fix the problem one have to use beforeClear callback of filterToolbar:

beforeClear: function () {
    $(this.grid.hDiv)
        .find(".ui-search-toolbar .ui-search-input>select[multiple] option")
        .each(function () {
            // unselect all options in <select>
            this.selected = false; 
        }
    );

    $(this.grid.hDiv)
        .find(".ui-search-toolbar button.ui-multiselect")
        .each(function () {
            // synchronize jQuery UI Multiselect with <select>
            $(this).prev("select[multiple]").multiselect("refresh");
        }
    ).css({
        width: "98%",
        marginTop: "1px",
        marginBottom: "1px",
        paddingTop: "3px"
    });
}

演示演示了解决方法.如果jqGrid中的错误将得到解决，则可以像beforeClear回调中删除第一行树. ="nofollow">演示.

The demo demonstrates the workaround. If the bug in jqGrid will be solved then one could remove the first tree lines from the beforeClear callback like in the demo.
