    <form name="Shahab_Forms">

    </form>

Answer 1

JavaScript是区分大小写的。 Shahab_Forms与shahab_forms不同。您的代码中有2个错误：

1）caseSenstivity，即shahab_Forms与Shahab_Forms

2）您输入了错字：shahab_Form。您最后错过了“ s”。

下面是您的工作代码

 function Validator(){
            if(document.Shahab_Forms.TheCheckBox.checked)
            {
                alert("it's already Checked my Friend!");
            }
            else
            {
             alert("no it's not checked my friend");
            }
        }

   
 <form name="Shahab_Forms">
            <input type="checkbox" name="TheCheckBox"/>
            <input type="button" value="Press Me" onclick="Validator();"/> 
    </form>

Answer 2

     function Validator(){
            if(document.shahab_Form.TheCheckBox.checked)
            {
                alert("it's already Checked my Friend!");
            }
            else
            {
             alert("no it's not checked my friend");
            }
        }

    <form name="Shahab_Forms">
            <input type="checkbox" name="TheCheckBox"/>
            <input type="button" value="Press Me" onclick="Validator();"/> 
    </form>
