<!--用于禁用MSIE和Chrome友好错误页的填充 -->异常说明
- 使用wangEditor编辑器，提交内容；
- 正常数据的文本，正常提交；
- 外网使用时，上传图片或视频后，出现404页面，具体提示信息：
a padding to disable MSIE and Chrome friendly error page； - 内网使用时，正常；
异常排查
- 把所有精力放在解决“a padding to disable MSIE and Chrome friendly error page”是个错误，导致对NGINX的配置、内网外网都进行过怀疑和调试；
- 尤其是内网可用，外网不可用，更是导致跑了很多远路；
- 其实，问题的关键在于上传图片后，
正常的路由无法获取，就代表网络层被阻断了。 - 逐行调试，对代码转义后，一切正常。

转义函数
/*HTML代码转义*/
function escapeHtml(unsafe) {return unsafe.replace(/&/g, "&").replace(/</g, "<").replace(/>/g, ">").replace(/"/g, """).replace(/'/g, "'");
}
字段调用
$.ajax({type: "post",url: "?m=Forum&a=forumDeal&act=add",async: true,data: {section: $('#sect_name').val(),forum_title: $('#forum_title').val(),forum_abstract: $('#forum_abstract').val(),forum_age: $('#forum_age').val(),forum_sex: $('#forum_sex').val(),forum_chief: $('#forum_chief').val(),forum_subjective: escapeHtml(forum_subjective),forum_objective: escapeHtml(forum_objective),forum_assess: escapeHtml(forum_assess),forum_treat: escapeHtml(forum_treat),forum_effect: $('#forum_effect').val(),forum_evaluate: escapeHtml(forum_evaluate)},dataType: "json",success: function (res) {//console.log(res);if (res.code == 0) {layer.msg(res.msg, {icon: 2, time: 2000});} else {layer.msg(res.msg, {icon: 1, time: 2000}, function () {window.parent.location.href = "?m=My&a=myForum";});}}, error: function (err) {console.log(err)}});
