我正在做一个PHP + Mysql + Jquery编辑表单。我想知道在编辑字段并保存在数据库中后，jquery如何在字段中显示新数据而不刷新整个页面。我目前使用：
$(document).ready(function (e) {
$('form[name=form_edit]').on('submit',(function(e) {
e.preventDefault();
var formData = new FormData(this);
var form = $(this);
var conte = $('#form-edit');
$.ajax({
type:'POST',
url: '<?php echo ROOT_URL ?>/sites/crud-sites',
data:formData,
cache:false,
contentType: false,
processData: false,
success:function(data){
location.reload();
}
});
}));
});
location.reload（）;它可以工作，但它会重新加载整个页面。我只想重新加载字段。
仍然不太明白该怎么做。我的表单看起来像这样： 我想要更新的主要字段是图像字段。

将新更新的数据发送到ajax响应，然后您可以将值设置为表单。
