Change form submit action and then submit the form
提问by Radish
I'm trying to add a button to my form that would essentially run some different php code than my regular form submission code, that would, instead of emailing me the form, convert my page into a nice pdf ready to print. I have everything working except that pressing the button is giving me an error.
我正在尝试向我的表单添加一个按钮，该按钮基本上会运行一些与我的常规表单提交代码不同的 php 代码，而不是通过电子邮件将表单发送给我，而是将我的页面转换为准备好打印的漂亮 pdf。我一切正常，只是按下按钮给我一个错误。

Here's the code:
这是代码：
<form id="adaugareanunt" name="adaugareanunt" action="mailerPDF.php" method="post">
<table width="535" border="0" cellspacing="2" cellpadding="3">
<tr class="TrDark">
//... more form code
and for the button:
和按钮：
<div style="text-align:right"><img src="images/print-button.png" onClick="chgAction()" width="60px" height="20px"></div>
with the script:
使用脚本：
<script language="JavaScript" type="text/JavaScript">
function chgAction()
{
document.getElementById["adaugareanunt"].action = "mailerXFDF.php";
document.getElementById["adaugareanunt"].submit();
document.getElementById["adaugareanunt"].action = "mailerPDF.php";
}
</script>

Adaugareanunt是一个对象键：getElementById["adaugareanunt"]
"Adaugareanunt"is a stringpassed to the getElementById()methodas argument:getElementById('adaugareanunt')?
"Adaugareanunt"是一个字符串传递给getElementById()方法的参数：getElementById('adaugareanunt')？

Change the block brackets : []
更改块括号：[]
To
到
The round brackets : ()
圆括号：()
Square brackets means new Array.
方括号表示新数组。
var ar = newArray( " a " , " b " ) ;
var ar = [ " a " , " b " ] ;
