发布这个因为我发现了很多jquery答案,但没有原始的javascript答案。
所以我有一个函数将评论发布到评论部分,我希望评论部分在发表评论后刷新,但由于某种原因,我的代码无效。
加载评论部分的代码:
function loadCommentSection() {
console.log("loading section")
imgid = imgid.replace("img/pic (", "");
imgid = imgid.replace(").jpg", "");
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("commentsection").innerHTML = this.responseText;
}
};
xhttp.open("GET", "commentsection.php?imgid=" + imgid, true);
xhttp.send();
}
以及提交评论的代码:
function submitComment() {
var title = document.getElementById("title").value;
var name = document.getElementById("name").value;
var comment = document.getElementById("comment").value;
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("msg").innerHTML = this.responseText;
}
};
xhttp.open("GET", "comment.php?imgid=" + imgid + "&title=" + title + "&comment=" + comment + "&name=" + name, true);
xhttp.send();
loadCommentSection();
}
问题是submitComment函数中的loadCommentSection函数没有执行。
答案 0 :(得分:4)
您应该允许将评论发送到服务器并在致电loadCommentSection
之前进行注册。因此,最好在响应可用时调用它:
function submitComment() {
var title = document.getElementById("title").value;
var name = document.getElementById("name").value;
var comment = document.getElementById("comment").value;
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("msg").innerHTML = this.responseText;
loadCommentSection(); // <<---- moved here.
}
};
xhttp.open("GET", "comment.php?imgid=" + imgid + "&title=" + title + "&comment=" + comment + "&name=" + name, true);
xhttp.send();
}
