没有数据的ajax请求不起作用

我正在尝试使用ajax删除照片,当删除照片时立即显示默认图像,到目前为止,我完成了php端,但ajax部分无法正常工作。 如何在没有数据类型的情况下发出ajax请求?

function delete_image() { $.ajax({ type: "POST", url: "target.php?page=delete", cache: false, success: function(response) { var $divs = $("
" + response + "
"); $("#phd").fadeOut('slow'); $(".suc_pic").fadeIn('slow').empty().append($divs.find("#msg"));//the default picture fades in once the photo is deleted. } }); }

尝试在数据部分中移动“page = delete”

 function delete_image() { $.ajax({ type: "POST", url: "target.php", cache: false, success: function(response) { var $divs = $("
" + response + "
"); $("#phd").fadeOut('slow'); $(".suc_pic").fadeIn('slow').empty().append($divs.find("#msg"));//the default picture fades in once the photo is deleted. }, data: {page='delete'} }); }
