Javascript 基于选中的复选框列表项显示或隐藏一个或多个控件

对不起，专家们，我今天花了一半时间在谷歌上搜索，但我可以找到任何有用的解决方案

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

我有一个ID为ckRequestReview的checkboxList控件。此复选框列表控件有三项

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

我们的要求是，如果用户单击其中一个项目，则显示两个与之相关的文本框

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

如果用户选中所有三个复选框项，则显示所有六个文本框控件

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

到目前为止，只有三个在工作

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

以下是需要发生的事情：

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

在页面加载时，默认情况下，所有六个文本框控件都隐藏

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

用户选中职务复选框项，两个控件，txtitlechange和txtitle控件可见

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

或者用户检查支付范围复选框项，并显示两个控件，txtPayGrade更改和txtPayGrade

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

或者用户选中Class复选框项和两个控件，txtClassSpecChange和txtclassion

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

或者用户选中所有三个复选框项，并且所有六个文本框控件都可见

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

到目前为止，在列出的六个文本框控件中，只有这三个控件工作正常：

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';

当复选框被选中或未选中时，其他三个什么也不做。你知道我做错了什么吗

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);

        } else {

正当理由

您正确地向JS传递了三个参数，但只处理了2个。换成这个

<script type="text/javascript">
    function ShowHide(chk, txt) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        //Check if checkbox is checked or not
        if (chk.checked) {
            //Show the Textbox
            ctrltxt.style.display = 'block';
        } else {
            //Hide the textbox
            ctrltxt.style.display = 'none';
        }
    }
</script>

<script type="text/javascript">
    function ShowHide(chk, txt,txt2) {
        //Get the Textbox based on selected checkbox
        ctrltxt = document.getElementById(txt);
        ctrltxt2= document.getElementById(txt2);
        //Check if checkbox is checked or not
        if (chk.checked) {
           //Show the Textbox
           ctrltxt.style.display = 'block';
           ctrltxt2.style.display = 'block';
         } else {
           //Hide the textbox
           ctrltxt.style.display = 'none';
           ctrltxt2.style.display = 'none';
         }
     }

函数ShowHide（chk、txt、txt2）{
//根据选中的复选框获取文本框
ctrltxt=document.getElementById（txt）；
ctrltxt2=document.getElementById（txt2）；
//检查复选框是否选中
如果（已检查）{
//显示文本框
ctrltxt.style.display='block'；

}否则{
//隐藏文本框
