Question

我想通过基本文本输入并使用多选字段来过滤下表。

示例：http://jsfiddle.net/bghouse/6by1f9cx/

<form class="job-search-form">
    <input class="search-keyword" type="text" placeholder="Enter job title or keyword">
</form>

<label for="search-category search-select">
    <select name="select-category" class="select-category" multiple style="width: 100%;" id="search-category">
        <option value="Engineering - Software">Engineering - Software</option>
        <option value="Engineering - Hardware">Engineering - Hardware</option>
        <option value="Sales">Sales</option>
        <option value="Other">Other</option>
        <option value="Tech Support">Tech Support</option>
    </select>
    <a href="#" class="arrow"></a>
</label>

<table class="job-posts-table" role="grid">
    <thead>
        <tr role="row" class="tablesorter-headerRow">
            <th class="col1 tablesorter-header">
                <div class="tablesorter-header-inner">Job Title</div>
            </th>
            <th class="col2 tablesorter-header">

            </th>
            <th class="col3 tablesorter-header">
                <div class="tablesorter-header-inner">Location</div>
            </th>
        </tr>
    </thead>
    <tbody class="job-posts-body" aria-live="polite" aria-relevant="all">
        <tr role="row">

问题1

我想改进搜索输入以使用过滤器功能，而不要区分大小写。或最有意义的功能。

它可以搜索整行，而不必只是标题。

我目前正在使用：contains对其进行过滤，并且效果不佳，因为它区分大小写，而且似乎应该有更好的选择。

var input_val = '';
$('.search-keyword').on('keyup',function(){
    input_val = $(this).val();
    if(input_val.length >= 3){
        $('.job-posts-body tr').hide()
        $('.job-posts-body tr:contains("'+input_val+'")').show();
    }else{
        $('.job-posts-body tr').show()
    }
})

问题2

根据类别使用过滤器功能或任何有意义的过滤器表。

Im使用多重选择2。它返回一个类别数组。

// select input for category    
$('.select-category').on('change',function(){
    console.log( $(this).val() );// array of categories
    // filter table with the above array for the category column
})

// select input for location
$('.select-location').on('change',function(){
    console.log( $(this).val() );// array of locations
    // filter table with the above array for the location column
})

Answer 1

问题1的答案包含在Chris Coyier的文章中（无双关语）： https://css-tricks.com/snippets/jquery/make-jquery-contains-case-insensitive/ CAVEAT：请务必阅读有关覆盖jQuery功能和创建新选择器（例如：Icontains）的评论。
