本文介绍了setTimeout没有执行表单提交的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 目标：延迟执行表单提交 代码（Javascript + JScript ASP）： <％ Response.Write（"< OBJECT ID =''IntraLaunch''STYLE =''display：none'' WIDTH = 0 HEIGHT = 0 CLASSID =''CLSID：0AE533FE- B805-4FD6-8AE1-A619FBEE7A23'' CODEBASE =''IntraLaunch.CAB＃version = 5,0,0,3''>"） 回复.Write（"< PARAM NAME =''ImageLoc''VALUE =''Null''>"） Response.Write（"< PARAM NAME =''ImageSrc' 'VALUE =''Null''>"） Response.Write（"< PARAM NAME ='''Run'' VALUE =''F ：\\Axys3 \\Clarity \\report1.bat''>"） Response.Write（"< PARAM NAME =''RunParms''VALUE =''''>"） Response.Write（"< PARAM NAME =''显示''VALUE = MAX''>"） Response.Write（"< / OBJECT>"） b $ b％> < script> 函数UpdateRec（theForm，rec）{ tmp_checked = 0; tmp_login = theForm.login.value; tmp_year = theForm.tmp_year.value; tmp_quarter = theForm.tmp_quarter.value; tmp_comm = theForm.comm.value; if（theForm [rec] .checked ）{ tmp_checked = 1; } theForm.target =" MyFrame"; theForm.action =" qr_update.asp？axys =" + rec +"& tmp_quarter =" + tmp_quarter +"& tmp_year =" + tmp_year +"& tmp_login =" + tmp_login + "& tmp_checked =" + tmp_checked +"& tmp_comm =" + tmp_comm; theForm.submit（）; document.body.style.cursor =''wait''; } 函数GenerateReport（theForm，rec，do_checkbox）{ document.IntraLaunch.RunParms = rec; IntraLaunch。 ExecuteIt（Null）; if（do_checkbox）{ oldcomm = theForm.comm.value; theForm .comm.value =" GSHOW"; theForm [rec] .checked = true; UpdateRec（theForm，rec）; theForm.comm.value = oldcomm; } tmp_year = theForm.tmp_year.value; tmp_quarter = theForm.tmp_quarter .value; theForm.target =" MyOtherFrame"; theForm.action =" generate.asp？quarter =" + tmp_quarter +"& year =" + tmp_year +"& axys =" + rec; var timer = setTimeout（" document。" + theForm.name +" .submit（）"，2000）; clearTimeout（计时器）; // alert（" GenerateReport表单对象名：" + theForm.name）; //document.updateform .submit（）; } 背景/说明： 这是一个任务状态跟踪网应用。这个 代码片段的目的是自动创建两个Axys报告作为文本 文件，将它们解析为PDF，并将它们整理成第三个PDF，所有这些都在 点击一个按钮。 GenerateReport是直接称为 的方法;对象声明和UpdateRec适用于您的 参考。这里的问题是通过IntraLaunch生成文本文件需要一些时间（一秒钟或两美元），我需要延迟 PDF操作（在generate.asp）直到完成。 代码本身是合理的 - 通过取消注释最后两行， 一切顺利，因为警报作为延迟。 我发现setTimeout根本没有执行表单提交： 我在< body onload =>中发出警报qr_update.asp和 generate.asp。 sans-setTimeout版本会弹出每个页面的警报， 但是如果我使用setTimeout，我只会收到qr_update的警报。不过，我感到很困惑，因为这似乎是通过setTimeout提交表格的正确语法 ： http://groups.google.com/groups?q=se...ft.com&rnum=10 请帮忙！ 谢谢， 米歇尔Goal: delay execution of form submitCode (Javascript + JScript ASP):<%Response.Write("<OBJECT ID=''IntraLaunch'' STYLE=''display : none''WIDTH=0 HEIGHT=0 CLASSID=''CLSID:0AE533FE-B805-4FD6-8AE1-A619FBEE7A23''CODEBASE=''IntraLaunch.CAB#version=5,0,0,3''>")Response.Write("<PARAM NAME=''ImageLoc'' VALUE=''Null''>")Response.Write("<PARAM NAME=''ImageSrc'' VALUE=''Null''>")Response.Write("<PARAM NAME=''Run''VALUE=''F:\\Axys3\\Clarity\\report1.bat''>")Response.Write("<PARAM NAME=''RunParms'' VALUE=''''>")Response.Write("<PARAM NAME=''Display'' VALUE=MAX''>")Response.Write("</OBJECT>")%><script>function UpdateRec(theForm, rec) {tmp_checked = 0;tmp_login = theForm.login.value;tmp_year = theForm.tmp_year.value;tmp_quarter = theForm.tmp_quarter.value;tmp_comm = theForm.comm.value;if(theForm[rec].checked) {tmp_checked = 1;}theForm.target = "MyFrame";theForm.action = "qr_update.asp?axys=" + rec + "&tmp_quarter=" +tmp_quarter + "&tmp_year=" + tmp_year + "&tmp_login=" + tmp_login +"&tmp_checked=" + tmp_checked + "&tmp_comm=" + tmp_comm;theForm.submit();document.body.style.cursor = ''wait'';}function GenerateReport(theForm, rec, do_checkbox) {document.IntraLaunch.RunParms = rec;IntraLaunch.ExecuteIt("Null");if (do_checkbox) {oldcomm = theForm.comm.value;theForm.comm.value = "GSHOW";theForm[rec].checked = true;UpdateRec(theForm, rec);theForm.comm.value = oldcomm;}tmp_year = theForm.tmp_year.value;tmp_quarter = theForm.tmp_quarter.value;theForm.target = "MyOtherFrame";theForm.action = "generate.asp?quarter=" + tmp_quarter + "&year=" +tmp_year + "&axys=" + rec;var timer = setTimeout("document."+theForm.name+".submit()", 2000);clearTimeout(timer);//alert("GenerateReport form object name: " + theForm.name);//document.updateform.submit();}background/explanation:This is a task-status tracking web application. The purpose of thiscode snippet is to automatically create two Axys reports as textfiles, parse them into PDFs, and collate them into a third PDF, all onthe click of a button. GenerateReport is the method that''s calleddirectly; the object declaration and UpdateRec are there for yourreference. The issue here is that it takes some time (a second ortwo) to generate the text files via IntraLaunch, and I need to delaythe PDF operations (performed in generate.asp) until this is done.The code itself is sound -- by uncommenting the last two lines,everything functions smoothly, since the alert acts as a delay.I have found that setTimeout is not executing the form submit at all:I placed alerts in <body onload=> of both qr_update.asp andgenerate.asp. The sans-setTimeout version pops an alert for each page,but if I use setTimeout, I only get an alert for qr_update. I ampuzzled, though, because this seems to be the correct syntax for formsubmission via setTimeout: http://groups.google.com/groups?q=se...ft.com&rnum=10Please help!Thanks,Michelle推荐答案 Mic说：Mic said: var timer = setTimeout（" document。" + theForm.name +" .submit（）"，2000）; clearTimeout（计时器）;var timer = setTimeout("document."+theForm.name+".submit()", 2000);clearTimeout(timer); setTimeout没有插入延迟。 它安排在指定的延迟后执行的某些任务。 执行立即进入下一行。 这两行说： 1.等待两秒钟，然后提交佛rm。 2.没关系。setTimeout doesn''t insert a delay.It schedules some task to be performed after a specified delay.Execution proceeds immediately to the next line.Those two lines say:1. Wait two seconds, and then submit the form.2. Nevermind.是的，修好了。 1）我觉得迟钝了 2）你很棒 - 谢谢!!!!! :-)Yep, that fixed it.1) I feel retarded2) You''re awesome -- thanks!!!!!:-) Lee写道：Lee wrote: Mic说： var timer = setTimeout（" document。" + theForm.name +" .submit（）"，2000）; clearTimeout（计时器）;var timer = setTimeout("document."+theForm.name+".submit()", 2000);clearTimeout(timer); setTimeout没有插入延迟。它安排了一些在指定的延迟之后执行的任务。 setTimeout doesn''t insert a delay. It schedules some task to be performed after a specified delay. 实际上，如果提供了一个字符串作为第一个参数，setTimeout（）会调度 表达式在指定的延迟后进行评估。如果提供了一个 函数对象引用，则调用引用的函数， 使用setTimeout（）的第三个和后面的参数作为 $ b的参数$ b函数[仅限JavaScript 1.2 + / Gecko-DOM; IE-DOM确实支持从v5.0开始的函数引用，但没有支持日期的其他参数 （IE 6.0 SP-1） - setTimeout（alert，2000 ，42）在IE中产生一个空的消息框 ，但不在NN4 + / Mozilla中。] 但是，使用的表达式不是最佳的document.FormName不是符合标准的参考（即未在W3C-DOM Level 1+中指定）。 而是指定document.forms [" FormName"]，因此更好的 声明是 var timer = setTimeout（" document.forms [''" + theForm .name +"'']。submit（）"，2000）; 或 var timer = setTimeout（document.forms [theForm.name] .submit，2000）; 然而，如果 在访问它之前有document.forms [theForm.name] .submit（）。对于 第一个变体，如在超时中使用的那样，如果窗口的内容在此期间发生了变化，那么纯粹的，未经检查的声明 可能会失败某些原因是。对于第二个变体，查找路径的一部分可能是 非引用，已经导致分配时出现脚本错误。 因此应该使用 函数submitForm（sFormName） { var f，t; if（document && document.forms &&（f = document.forms [sFormName]） &&（（t = typeof f.submit）==" function" || t ==" object"） { f.submit（ ）; } } var timer = setTimeout（" submitForm（" + theForm.name +" ）"，2000）; PointedEarsActually, if provided a string as first argument, setTimeout() schedulesthat expression to be evaluated after a specified delay. If provided aFunction object reference instead, the function referred to is called,using the third and following arguments of setTimeout() as arguments forthe function [JavaScript 1.2+/Gecko-DOM only; the IE-DOM does supportfunction references from v5.0 on, but not additional arguments to date(IE 6.0 SP-1) -- setTimeout(alert, 2000, 42) yields an empty message boxin IE, but not in NN4+/Mozilla.]However, the used expression is suboptimal as document.FormName is not astandards compliant reference (i.e. not specified in W3C-DOM Level 1+).Instead document.forms["FormName"] is specified there, thus the betterstatement is eithervar timer =setTimeout("document.forms[''"+theForm.name+"''].submit()", 2000);orvar timer =setTimeout(document.forms[theForm.name].submit, 2000);Yet it would be much better to check (calling a user-defined method) ifthere is document.forms[theForm.name].submit() before accessing it. Forthe first variant, as used in a timeout, the pure, unchecked statementis likely to fail if the window''s content has changed in the meantime forsome reason. For the second variant, a part of the lookup path may be anon-reference anyway, already causing a script error on assignment.Therefore one should usefunction submitForm(sFormName){var f, t;if (document&& document.forms&& (f = document.forms[sFormName])&& ((t = typeof f.submit) == "function"|| t == "object"){f.submit();}}var timer = setTimeout("submitForm(" + theForm.name + ")", 2000);PointedEars 这篇关于setTimeout没有执行表单提交的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
