Javascript 使用onclick和onsubmit提交表单
我正在尝试为我的公司设置一个“点击聊天”系统。它需要一个表单,从用户那里获取一些信息。提交表单时,应该使用.js文件中的脚本打开一个新窗口 我试图添加一些验证,这导致了onclick和onsubmit函数。当表单在未进行验证的情况下被subitted时,它会使用Javascript 使用onclick和onsubmit提交表单,javascript,forms,function,onclick,onsubmit,Javascript,Forms,Function,Onclick,Onsubmit,我正在尝试为我的公司设置一个“点击聊天”系统。它需要一个表单,从用户那里获取一些信息。提交表单时,应该使用.js文件中的脚本打开一个新窗口 我试图添加一些验证,这导致了onclick和onsubmit函数。当表单在未进行验证的情况下被subitted时,它会使用BG.startChatWithIssueForm(this.form,true)打开一个新窗口函数。但是,出于某种原因,当我包含onsubmit进行验证时,onclick会完全忽略它 我已经尝试用issueform嵌套BG.startc

我已经尝试用issueform嵌套BG.startchat(this.form,true)在formValidator()
函数的不同位置执行code>函数,但它仍然会导致文件下载提示,而不是打开新窗口
不知道我做错了什么。我已经研究了好几个星期了,似乎什么都没想到。Javascript绝对不是我的强项,因此任何帮助都将不胜感激
