从 j印功能中获取检查箱的价值归属
原标题:get value attribute of a checkbox from javascript function

我正在这样做:

function GETVALUE() 
{
 if(document.getElementById("requirenewpage").checked == true)
    {
        document.getElementById("requirenewpage").value;    
        var cval= parseInt(document.getElementById("requirenewpage").value);

    }
}

页: 1

<input type="checkbox" id="requirenewpage" unchecked   value= "GETVALUE();" >

我需要插入一张从检查箱的估价金字表中提取的零或1张单。

它总是在数据库中插入0,尽管正在确定GETVALUE(......)的功能价值为1。

最佳回答

I m shocked that nobody has answered this correctly yet... Change the checkbox to the following:

<input type="checkbox" id="requirenewpage" name="requirenewpage" value= "1" />

如果你希望以所附姓名的形式提交该要素,则输入元件的识别资料将被用于打字和打字 only

问题回答

Actually you don t need any of this i think. You can use this html:

  <input type="checkbox" id="requirenewpage"  value= "1" >

检查箱将给服务器1美元的价值(,如果检查<>/strong>,否则将获得任何电码(相应的<代码>_POST[要求新页][或_GET[要求新页][]的打上)。

如果检查箱被检查,其价值被送至服务器,并且用检查箱的名称和检查箱的价值创建“POST”阵列中的钥匙。

服务器:

$chkboxval = 0;

if (isset($_POST[ requirenewpage ])){
     $chkboxval = $_POST[ requirenewpage ];
}

你对你来说错了。 更改<条码>箱 代码

<input type="checkbox" id="requirenewpage" "unchecked"   value= "GETVALUE();" >

纽约总部

<input type="checkbox" id="requirenewpage" onclick= "GETVALUE();" >
