Javascript、Datatables、jmhighlight 和多个搜索

Question

我正在使用 DataTables plugin，并且我在 table 的每一列中创建了多个搜索框。

然后我应用 jmHighlight plugin 来突出显示搜索结果。

现在我想请教您如何修改jmHighlight代码以获得：

突出显示的不同跨度和颜色；
并获得突出显示的单词在没有突出显示的情况下不会return正常。

当我调用 jmhighlight() 函数时，我使用：

 function hlCountry (e) {   //"e" is the number of col activated for search
     var $keyword = $('#col'+e+'_filter').val(); //this recover word inserted
     console.log($keyword); //this is just for test

     $("#example tbody #Col"+e+"_tab").jmRemoveHighlight(); //here I call jmRemoveHighlight function restricting search in specify col of table
     $("#example tbody #Col"+e+"_tab").jmHighlight($keyword);  //here I call jmHighlight function restricting search in specify col of table
 }

我试图在 jquery.jmHighlight.min.js 中搜索 jmRemoveHighlight() 和 jmHighlight()（文件包含在页面中）。遵循代码：

这段代码对我来说真的很复杂。我以为我会在代码中找到 jmRemoveHighlight() 和 jmHighlight()，但没有。

我当然应该在 <span> 和 <class name> 上工作，但我不知道具体怎么做。

写的插件开发者：

You can also highlight multiple keywords/phrases with different classes in the context. Just clone this code below for each keyword. Pass an array filter in the option-object. The filter-array should contain all selectors that should be ignored.

但是我做不到。能告诉我解决这个问题的方向吗？

我只是想指出这个问题已经在这里解决了： https://github.com/julmot/jmHighlight/issues/8

documentation 包含一些用法示例，向您展示如何将 jmHighlight 与 DataTables 结合使用以及如何突出显示普通 table 列。
