如何拉取由 javascript 函数创建的元素的 innerHTML
How pull innerHTML of element created by javascript function
问题:
我有一个 ID 为 "tableholder" 的 div 元素,它纯粹是为了将输出保存在 javascript 函数上,该函数通过 ajax 从 PHP 文件。
在 tableholder 元素中,是一个 list.js table,如果我们简单地包含他 php 文件而不是通过 ajax 调用它,它就可以工作并通过 innerHTML = "".
进行设置
如何使用动态创建的 tableholder div 的 innerHTML 的内容?
目前代码:
PHP 文件调用:
<?php
// Connection details for the database being called.
include 'connection.php';
// Putting the query to the database in a variable called "$assets".
$assets = "SELECT * FROM assetregister.getassets";
$assetPull = $conn->query($assets);
$output = "";
// Pulling all of the details from the database and displaying them on the page within the inidividual divs.
if ($assetPull->num_rows > 0) {
$output .= "<div id='users'>";
$output .= "<input class='search form-control mt-2' placeholder='Search...' />";
$output .= "<div class='m-2'>";
$output .= "<button class='sort btn' data-sort='model'>Sort By Model</button>";
$output .= "<button class='sort btn ml-2' data-sort='domain'>Sort By Domain</button>";
$output .= "<button class='sort btn ml-2' data-sort='location'>Sort By Location</button>";
$output .= "</div>";
$output .= "<table class='table table.hover list'>";
$output .= "<thead>";
$output .= "<th style='text-align: center;'>Model</th>";
$output .= "<th style='text-align: center;'>Serial Number</th>";
$output .= "<th style='text-align: center;'>Asset Number</th>";
$output .= "<th style='text-align: center;'>Domain</th>";
$output .= "<th style='text-align: center;'>Location</th>";
$output .= "<th style='text-align: center;'>Type</th>";
$output .= "</thead>";
while ($row = $assetPull->fetch_assoc()) {
$output .= "<tbody class='list' style='text-align: center;'>";
$output .= "<td class='model'>" . $row['modelName'] . "</td>";
$output .= "<td class='serialNumber'>" . $row['serialNumber'] . "</td>";
$output .= "<td class='assetNumber'>" . $row['assetNumber'] . "</td>";
$output .= "<td class='domain'>" . $row['domain'] . "</td>";
$output .= "<td class='location'>" . $row['locationName'] . "</td>";
$output .= "<td class='type'>" . $row['type'] . "</td>";
}
$output .= "</tbody>";
$output .= "</table>";
$output .= "</div>";
// If there is no rows in the table that is being called then they will display 0 Results... See below.
} else {
$output .= "0 results";
}
echo $output;
$conn->close();
?>
这有效:
<div class="container-fluid">
<div class="container">
<div class="row">
<main class="col-12" style="margin-top: 80px;">
<button class="btn btn-primary" onclick="assetSubmit()" style="width: 100%;">Add An Asset</button>
<?php include 'scripts/getAsset.php'; ?>
</main>
</div>
</div>
</div>
<script>
populatetable('tableholder');
window.onload = function () {
var options = {
valueNames: ['model', 'serialNumber', 'assetNumber', 'domain', 'location', 'type']
};
var userList = new List('users', options);
};
</script>
这会输出 table 并且所有 list.js 函数都按预期正常工作。
这行不通:
<div class="container-fluid">
<div class="container">
<div class="row">
<main class="col-12" style="margin-top: 80px;">
<button class="btn btn-primary" onclick="assetSubmit()" style="width: 100%;">Add An Asset</button>
<!-- Pulling in the results of the assets (most recent assets) -->
<div id="tableholder"></div>
<!-- end -->
</main>
</div>
</div>
</div>
<!-- PHP include for the footer -->
<?php include 'assets/layout/footer.php'; ?>
<!-- end -->
<script>
populatetable('tableholder');
window.onload = function (){
var options = {
valueNames: [ 'model', 'serialNumber', 'assetNumber', 'domain', 'location', 'type']
};
var userList = new List('users', options);
};
function populatetable(name){
$.ajax({
url: "scripts/getAssets.php",
success: function(data){
document.getElementById(name).innerHTML = data;
}
})
}
</script>
我可以假设:
从我用来测试代码的各种 console.log 行和 php 回声来看,问题似乎是 javascript 命令启动 list.js table 无法找到由 document.getElementById(name).innerHTML = data;
在 populatetable() 函数中创建的 "user" table。我知道这一点是因为下面显示空白:
console.log(document.getElementById(tableholder).innerHTML);
我做错了什么,或者无法提取动态创建元素的 innerHTML 数据?
问题是当您调用 List()
时,ajax 调用尚未完成,因为它是异步的。
试试这个:
var options = {
valueNames: ['model', 'serialNumber', 'assetNumber', 'domain', 'location', 'type']
};
var userList;
$(document).ready(function() {
populatetable('#tableholder');
});
function populatetable(id) {
$.ajax({
url: "scripts/getAssets.php",
success: function(data) {
$(id).html(data);
userList = new List('users', options);
}
});
}
在这里,我在任何有用的地方都使用 jQuery,只有在实际插入数据后才调用 List()
。
另请注意,就像我在评论中提到的那样,您需要将 <tbody>
行移到循环之外。
