我写了一个由Javascript建模的网站。在网页中,我写了一条消息,以防止用户激活JS。在我的JS代码中,我在第一步删除了这个节点。问题是效果会在页面完全加载之前出现......
var modelerBody = null;
var loadingNode = document.createElement("div");
loadingNode.appendChild(document.createTextNode(messageGeneric['loading']));
loadingNode.setAttribute("id", "loading");
window.onload = function() {
document.getElementById("jsDisabled").remove()
var body = document.getElementsByTagName("body")[0];
body.insertBefore(loadingNode, body.childNodes[0]);
inflateForms();
modelerBody = new Modeler.Screen(body.childNodes[1]);
modelerBody.modelize();
// Remove Loading message
body.childNodes[0].remove();
}
我如何解决这个问题? 对不起我的英语我正在学习它......

您可以在元素加载之前运行Javascript,方法是将脚本标记放在要删除的div上方,但由于尚未加载div,因此无法找到div。在元素加载之前无法编辑元素。
<?php
if (isset($_POST['submit'])) {
$id = $_GET["section"];
$about_me = "../include/about_me.php";
$providers_2 = "../include/2providers.php";
$more_providers = "../include/more_proiders.php";
$section_change = $_POST["section_change"];
$query = "UPDATE sections SET ";
$query .= "`File Path` = '{$section_change}' ";
$query .= "WHERE id = '{$id}' ";
$query .= "LIMIT 1";
$result = mysqli_query($link, $query);
if ($result && mysqli_affected_rows($link) == 1) {
// Success
$_SESSION["message"] = "Section Changed.";
redirect_to("../index.php?admin=true");
} else {
// Failure
echo "System Failure. Please try again later. If problem persists please notify your admin at aqeke.com/powerplaylife-help";
}
} else {
print_r($_POST);
}
?>
标记可用于此目的。包装元素以显示用户是否未启用Javascript。
