询问你是否确定要提交？ JavaScript的？ [英] Ask if you are sure you want to submit? JavaScript?

问题描述

  //其他的东西在这里 - 不重要
 echo< td> ;< form action ='redeem.php'method ='post'id ='form'>< input type ='hidden'name ='redeem'value ='1'/>< input type ='隐藏'name ='id'value ='。 $ id。 '/>< input type ='submit'name ='Redeem'value ='Redeem'>< / form>< / td>; 
} else {
 echo'< td>< form action ='redeem.php'method ='post'id ='form'>< input type ='hidden'name =' redeem'value ='0'/>< input type ='hidden'name ='id'value ='。 $ id。 '/>< input type ='submit'name ='Un-Redeem'value ='Un-Redeem'>< / form>< / td>; 
 //其他东西在这里 - 不重要
  

我想改变它以便当您按下：

a）'兑换'提交按钮时，它会提醒您说：您确定要兑换吗？
b）'Un-Redeem'提交按钮它会提醒你说：你确定要Un-Redeem吗？

我尝试了其中的几个，其中包括ONCLICK上的提交但没有工作..我相信这是因为我在ECHO中，我不得不删除（）引号停止发生功能。

任何人都知道另一种方式我可以做到这一点？

解决方案

这是解决方案：

  //其他东西在这里 - 不重要
 echo< td>< form action ='redeem.php'method ='post'id =' '< input type ='hidden'name ='redeem'value ='1'/>< input type ='hidden'name ='id'value ='。$ id 。'/> 
< input type ='submit'name ='Redeem'value ='Redeem'onclick =return confirm（'您确定要兑换吗？'）>< / form>< td>; 
} else {
 echo< td>< form action ='redeem.php'method ='post'id ='form'>< input type ='hidden 'name ='redeem'value ='0'/>< input type ='hidden'name ='id'value ='。$ id。'/> 
< input type ='submit'name ='Un-Redeem'value ='Un-Redeem'onclick =return confirm（'您确定要Un-Redeem？'）>< / form>< / td>; 
 //其他东西在这里 - 不重要
  

编辑：
在这里添加了转义字符：

  //其他东西这里 - 不重要
 echo< td>< form action ='redeem.php'method ='post'id ='form'>< input type ='hidden'name ='redeem'value ='1'/>< input type ='hidden'name ='id'value ='。$ id。'/> 
< input type ='submit'name ='Redeem'value ='Redeem'onclick = \return confirm（'您确定要兑换？'）\>< / form> ;< / td>; 
} else {
 echo'< td>< form action ='redeem.php'method ='post'id ='form'>< input type ='hidden'name ='redeem'value ='0'/>< input type ='hidden'name ='id'value ='。$ id。'/> 
< input type ='submit'name ='Un-Redeem'value ='Un-Redeem'onclick = \return confirm（'您确定要Un-Redeem？'）\ >< / form>< / td>; 
 //其他东西在这里 - 不重要
  

I currently have this.

 //other stuff up here - not important
    echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='1' /><input type='hidden' name='id' value='" . $id . "' /><input type='submit' name='Redeem' value='Redeem'></form></td>";
    } else {
    echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='0' /><input type='hidden' name='id' value='" . $id . "' /><input type='submit' name='Un-Redeem' value='Un-Redeem'></form></td>";
//other stuff down here - not important

and I want to change it so that when you press:
a) the 'Redeem' SUBMIT button it alerts you saying, "Are you sure you want to Redeem?"
b) the 'Un-Redeem' SUBMIT button it alerts you saying, "Are you sure you want to Un-Redeem?"

I have tried a few of them including the ONCLICK on the submit but none worked.. and I believe that is because I have it in an ECHO and I had to remove the (") quotation marks which stopped the function from happening.

Anyone know another way I can do it?

解决方案

Here is the solution :

     //other stuff up here - not important
        echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='1' /><input type='hidden' name='id' value='" . $id . "' />
              <input type='submit' name='Redeem' value='Redeem' onclick="return confirm('Are you sure you want to Redeem?')"></form></td>";
        } else {
        echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='0' /><input type='hidden' name='id' value='" . $id . "' />
              <input type='submit' name='Un-Redeem' value='Un-Redeem' onclick="return confirm('Are you sure you want to Un-Redeem?')" ></form></td>";
    //other stuff down here - not important

Edit: Added escaping character in here:

 //other stuff up here - not important
        echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='1' /><input type='hidden' name='id' value='" . $id . "' />
              <input type='submit' name='Redeem' value='Redeem' onclick=\"return confirm('Are you sure you want to Redeem?')\"></form></td>";
        } else {
        echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='0' /><input type='hidden' name='id' value='" . $id . "' />
              <input type='submit' name='Un-Redeem' value='Un-Redeem' onclick=\"return confirm('Are you sure you want to Un-Redeem?')\" ></form></td>";
    //other stuff down here - not important
