首先获取xmlHttp //创建xmlHttp function createXmlHttp() { var xmlHttp = null; if (window.ActiveXObject) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } else if (window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); } return xmlHttp; } 如果使用get方法的话，可以写作: function a(number){ var xmlHttp = createXmlHttp(); xmlHttp.onreadystatechange = function() { if (xmlHttp.readyState == 4) { if (xmlHttp.status == 200) { } } }; var url = "a.action?a.number="+number; xmlHttp.open("GET", url, true); xmlHttp.send(null); } 如果使用post方法的话，可以写作: function b(number){ var xmlHttp = createXmlHttp(); xmlHttp

问题 I've got a form which I retrieve data for in form.cleaned_data. I wish to render this data to another page for the submitter to review before it is entered in the DB. Now, I can just use render(request,"xyz.html","datax":form.cleaned_data} to render it to the user, but I am stuck at how to re-submit this data as POST from this page. How should I store this data in the next page so that it can be resent to me with my "confirm" button. Please do not suggest form preview in django. I do not wish

With wslite this is what I do Map<String, String> headers = new HashMap<String, String>(["Authorization": request.token]) TreeMap responseMap def body = [amount: request.amount]

Why does Header Content-Type for POST request differ between chrome and firefox only in by “UTF-8” vs “utf-8”?

由 耗尽温柔 提交于 2021-02-07 20:19:41
问题 I am using Flask and Angular JS to process POST request and I am wondering why the Chrome request header has application/json;charset=UTF-8 compared to FireFox application/json;charset=utf-8 .

This is probably related to SO: MySQL UTF8 for Chrome, UTF8 for IE, but HEADER UTF8 for Chrome and UTF-8 for IE? but I wasn't able to understand completely. I am not using any meta tag in the html, maybe that is the
