本文介绍了执行表单提交功能的处理方法,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! 希望这是一个非常简单的问题!我有jQuery中的代码来监听要提交的页面上的特定表单,并在它出现时执行警报。即:表单本身没有ID,因此我将该表单定位在特定DIV ID。 $(#content form)。submit(function(){ alert(lorem ipsum dolor?); }); 不使用jquery就可以在javascript中执行此操作的语法是什么?例如,我有这个代码(下面),只是不确定如何侦听表单被提交来执行一个操作.. var submitform = document.getElementById(content)。getElementsByTagName(form); 谢谢! 解决方案 var要在跨浏览器中执行,不是破坏性的方式,它需要一些代码:提交formform = document.getElementById(content)。getElementsByTagName(form)[0], callback = function(){ alert(lorem ipsum dolor?); }; if(window.addEventListener){ submitform.addEventListener(submit,callback,false); //最新的浏览器} else if(window.attachEvent){ submitform.attachEvent(onsubmit,callback); // IE } else { submitform.onsubmit = callback; //销毁其他处理程序} Hopefully this is a pretty simple question! I've got the code working in jQuery to listen for a specific form on a page to be submitted and perform an alert when it is.. I.e.: The form itself doesn't have an ID so I am targeting the form within a specific DIV ID.$("#content form").submit(function() { alert("lorem ipsum dolor?");});What would be the syntax for performing this in javascript alone without using jquery? For example, I have this code (below) and just am unsure of how to listen for the form to be submitted to perform an action..var submitform = document.getElementById("content").getElementsByTagName("form");Thanks! 解决方案 To do it in a cross browser, not destructive way, it takes a bit of code:var submitform = document.getElementById("content").getElementsByTagName("form")[0], callback = function(){ alert("lorem ipsum dolor?"); };if(window.addEventListener){ submitform.addEventListener("submit", callback, false); // Most modern browsers} else if (window.attachEvent){ submitform.attachEvent("onsubmit", callback); // IE} else { submitform.onsubmit = callback; // Destroys other handlers} 这篇关于执行表单提交功能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! 05-28 04:35
