如果下面的代码有点长，最重要的是道歉，但我想我必须把它放出来让你看到它的功能。

我的问题是Save单击按钮时，无论文本框是否有值或为空，它总是打印 message Saved!。只是它不会验证文本框的值。有人可以告诉我我在哪里出错了。谢谢你。

我看到一些小东西不见了：

您忘记在此处连接变量： <input type='checkbox' name='delz[]' value='$wec' >

它应该是

`<input type='checkbox' name='delz[]' value='".$wec."' />`

或者

`<input type='checkbox' name='delz[]' value='{$wec}' />`

使用 javascript

function validation()  
{
var chks = document.getElementsByName('delz[]');//here delz[] is the name of the textbox

    for (var i = 0; i < chks.length; i++)
    {       
    if (chks[i].value=="")
    {
    alert("Please fillup atleast one textbox");
    chks[i].focus();
    return false;           
    }
    }

}
