更改表格提交行动，然后提交表格

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.

我想在我的表单中添加一个按钮，它可以运行一些不同于常规表单提交代码的php代码，它可以将我的页面转换成一个漂亮的pdf格式，以便打印。除了按下这个按钮会给我一个错误外，我什么都能做。

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:

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>

4 个解决方案

#1

Adaugareanunt is an object key:
getElementById["adaugareanunt"]

Adaugareanunt是一个对象键:getElementById[" Adaugareanunt "]

"Adaugareanunt" is a string passed to the getElementById() method as argument:
getElementById('adaugareanunt') ✓

“Adaugareanunt”是一个字符串传递到getElementById()方法作为参数:getElementById✓(“Adaugareanunt”)

#2

document.getElementById["adaugareanunt"]

change to

改变

document.getElementById("adaugareanunt")

#3

Change the block brackets : []

更改方括号:[]

To

来

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 " ] ;

#4

This works fine

这工作好

<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>
