在树结构中搜索

  • 772

有遇到过这种Bootstrap树视图树结构的有经验的同事，如果树非常大，如何最好地组织搜索，这样在使用搜索时，正好打开所需的分支和元素。

<div class="tree well">
    <ul>
        <li>
            <span><i class="icon-folder-open"></i> Theme</span> <a href="">ссылки место</a>
            <ul>
                <li>
                    <span><i class="icon-minus-sign"></i> Standard</span> <a href=""></a>
                    <ul>
                        <li>
                            <span><i class="icon-leaf"></i> Grand Child</span> <a href="">ссылки место</a>
                        </li>
                    </ul>

    有一个解决办法，我再细化一下，但本质和这个例子是一样的：

    <input type="text" id="search" />

<style>
  .highlight {
    background: red;
  }
</style>

<script>
$(function(){
$('#search').on('keyup', function (){
  var val = $(this).val().toLowerCase()
  if (val) {
    $('ul li span').each(function(idx, obj){
      if ($(obj).text().toLowerCase().indexOf(val) !== -1)
        $(obj).addClass('highlight')
      else
        $(obj).removeClass('highlight')
    })
  }
  else
    $('ul li span').removeClass('highlight')
})
})
</script>
