Question

我正在尝试以手动方式加载数据。

HTML文件非常基本：只是一个表和一个按钮来加载php脚本发送的数据（名为 actions.php ）：

<!doctype html>

<html>

<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script src="dist/handsontable.full.js"></script>
    <link rel="stylesheet" media="screen" href="dist/handsontable.full.css">
</head>

<body>

<div id="hot"></div>
<br />
<input id="try" type="button" value="Try" />

</body>

<script>
$(function() {
    var objectData = [
        {id: 1, name: 'Ted Right', address: ''},
        {id: 2, name: 'Frank Honest', address: ''}];

    $('#hot').handsontable({
        data: objectData,
        colHeaders: true,
        minSpareRows: 1
    });

    var hot = $("#hot").handsontable('getInstance');

    $("#try").click(function(){
        $.getJSON("actions2.php", function(result){
            console.log (objectData);
            console.log (JSON.parse(result));
            hot.render();
        });
    }); 

});
</script>

</html>

php也很基本

<?php
$result=array(
    array("id" => 5, "name" => "Bill Gates", "address"=>"zzz"),
    array("id" => 6, "name" => "Steve Jobs", "address"=>"xxx")
);

echo json_encode(json_encode($result));
?>

当我点击“尝试”按钮时， objectData 已更新，但不是表格，尽管 hot.render（）指令。

对我做错了什么的想法？

我找到了问题。

js脚本中缺少

.loadData 方法，并且php中有 json_encode 错误

这是一个有效的例子。

<html>

<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script src="dist/handsontable.full.js"></script>
    <link rel="stylesheet" media="screen" href="dist/handsontable.full.css">
</head>

<body>
    <div id="hot" />
    <br />
    <input id="go" type="button" value="Click me" />
</body>

<script>
$(function() {
    var objectData = [
        {id: 1, name: 'Ted Right', address: ''},
        {id: 2, name: 'Frank Honest', address: ''}];

    $('#hot').handsontable({
        data: objectData,
        colHeaders: true
    });

    var hot = $("#hot").handsontable('getInstance');

    $("#go").click(function(){

        $.getJSON("actions2.php", function(result){
            hot.loadData(result);
            hot.render();
        });
    }); 

});
</script>

</html>

和actions2.php文件

<?php
$result=array(
    array("id" => 5, "name" => "Bill Gates", "address"=>"zzz","ee"=>"zz"),
    array("id" => 6, "name" => "Steve Jobs", "address"=>"xxx")
);

echo (json_encode($result));
?>

Handsontable - 表未呈现
