我想知道如何改进此代码,以便在删除注释时不刷新页面。如果你在页面的一半删除了一条评论,它又会回到顶部,这会很烦人。
AJAX
function delete_(pid){
$.ajax({
type: "POST",
url: "../include/post.delete.php",
data: "pid="+pid,
success: function(){

});

您需要对刚刚删除的注释元素调用.remove()
。你需要弄清楚如何识别它。有一种方法:
function delete_(pid){
$.ajax({
type: "POST",
url: "../include/post.delete.php",
data: "pid="+pid,
success: function(){
// However you can identify the comment's div, and delete it by calling .remove()
// This is if it has a unique id
$("#comment-"+pid).remove();
}
});
}
否则,如果使用<a href="javascript:delete_(pid);">
,则可以添加类似<a href="javascript:delete_(pid, this);">
的parmeter。例如,通过这种方式,您可以通过$(the_element_you_passed_to_the_function).parents("div.the-comment-div-parent").remove()
访问该元素。
否则,如果使用此方法,则可以直接在$("a").click(function {});
中实现此函数。这取决于你。
