Javascript 使用jquery和json进行实时搜索
我想做一个实时搜索，然后选择这些建议进一步实施！但它不会在选择字段中输入值。换句话说，选项标记不起作用！！！ 这是代码Javascript 使用jquery和json进行实时搜索,javascript,jquery,Javascript,Jquery,我想做一个实时搜索，然后选择这些建议进一步实施！但它不会在选择字段中输入值。换句话说，选项标记不起作用！！！ 这是代码 <div class="container"> <h4 class="publish-work" >PUBLISHED WORKS AVAILABLE</h4> <br> <input type="search" class="search" name="search" > <br&

而不是这个键控功能， 您可以使用Jquery自动完成功能来轻松搜索。 试试那个
<div class="container">
<h4 class="publish-work" >PUBLISHED WORKS AVAILABLE</h4>
<br>
<input type="search" class="search" name="search" >
<br>
<br>
<table id="datalist" class="table table-bordered" style="height: 400px; overflow-y: auto;">
<thead>
<th>S.no</th>
<th>Name</th>
<th>Price</th>
</thead>
<tbody>

参考此我发现您的位置。json的数据不标准，它应该是这样的：
[
{
"name":"Barot Bellingham"
},
{
"name":"Jonathan G. Ferrar II"
},
{
"name":"Hillary Hewitt Goldwynn-Post"
},
{
"name":"Hassum Harrod"
},
{
"name":"Jennifer Jerome"
},
{
"name":"LaVonne L. LaRue"
},
{
"name":"Constance Olivia Smith"
},
{
"name":"Riley Rudolph Rewington"
},
{
"name":"Xhou Ta"
}
]
<div class="container">
<h4 class="publish-work" >PUBLISHED WORKS AVAILABLE</h4>
<br>
<input type="search" class="search" name="search" >
<br>
<br>

首先，我们将一个html文件设置为index.html
<div class="container">
<h4 class="publish-work" >PUBLISHED WORKS AVAILABLE</h4>
<br>
<input type="search" class="search" name="search" >
<br>
<br>
<table id="datalist" class="table table-bordered" style="height: 400px; overflow-y: auto;">
<thead>
<th>S.no</th>
<th>Name</th>
<th>Price</th>
</thead>
<tbody>
</tbody>
</table>
<div class="container">
<h4 class="publish-work" >PUBLISHED WORKS AVAILABLE</h4>
<br>
<input type="search" class="search" name="search" >
<br>
<br>
<table id="datalist" class="table table-bordered" style="height: 400px; overflow-y: auto;">
<thead>
<th>S.no</th>
<th>Name</th>
<th>Price</th>
</thead>
<tbody>
</tbody>
</table>
<div class="container">
<h4 class="publish-work" >PUBLISHED WORKS AVAILABLE</h4>
<br>
<input type="search" class="search" name="search" >
<br>
<br>
<table id="datalist" class="table table-bordered" style="height: 400px; overflow-y: auto;">
<thead>
<th>S.no</th>
<th>Name</th>
<th>Price</th>
</thead>
<tbody>
</tbody>
</table>
<div class="container">

<br>
<input type="search" class="search" name="search" >
<br>
<br>
<table id="datalist" class="table table-bordered" style="height: 400px; overflow-y: auto;">
<thead>
<th>S.no</th>
<th>Name</th>
<th>Price</th>

<tbody>

就是这样。我喜欢这个。在每次击键时加载JSON无论如何都是糟糕的编程！如何将external location.json文件中的jason数据转换为javascript？？？在保存Jquery函数的同一页面中声明json数据，而不是通过服务器更新location.json的其他文件。如何将json对象分配给javascript变量，如：var obj=[{name:b}，{name:c}，{name:d}，{name:e}，{name:f}]。
