向 w2ui 网格添加过滤器搜索按钮

Question

对于我的 w2ui 网格，我希望有几个搜索按钮来过滤数据是预定义的方式。 （例如，“Big West”按钮可搜索以“Big West”作为会议的行。

<button class="w2ui-btn" onclick="var obj = w2ui['grid']; obj.search({ field : 'conference', value : 'Big West', operator : 'contains', type: 'text' });">Big West</button>

当我单击此按钮时，数据不会改变。理想情况下，第一次点击会进行搜索，再次点击会取消搜索。

如果你使用 w2ui 网格，它有很棒的搜索按钮，但你需要在数据源文件中进行自定义以过滤我粘贴脚本的行 PHP 及其工作非常适合 w2ui 网格，并将简化整个过程，并将其用作后端并为您的工作进行适当的定制：
