如何使用 jquery/ajax 刷新 div 中的表格內容

Question

一旦從方法調用該函數，我需要您的幫助才能刷新 html 中的 div id="mytable" 。 目前，一旦使用以下幾行調用它，我就會加載整個頁面。

在我的 java 方法中，我使用以下行來調用 javascript 方法：

RequestContext.getCurrentInstance().execute("autoRefresh()"); 

html代碼：

<script type="text/javascript">
    function autoRefresh() {
        window.location.reload();
    }
</script>

<div id='mytable'>
    <h1 id='My Table'>
        <table></table>
    </h1>
</div>

Answer 1

您可以部分加載 HTML 頁面，在您的情況下是 div#mytable 中的所有內容。

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

更新代碼（如果您不希望它自動刷新）

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

Answer 2

使用此代碼

$(".table").load(location.href + ".table");
