Question

有没有一种方法可以使以下代码在同一页面上显示链接，而不是打开新页面上的链接？例如，如果我在文本字段中编写“project”并按下提交按钮，则 project.htm 链接将显示在页面上;如果我在文本框中写下“under”并按下提交按钮，则 underconstruction.htm 链接变为可见。

    <script Language="JavaScript">
    <!--
        function Blank_TextField_Validator() {
            // Check the value of the element named text_name from the form named text_form
            if (text_form.text_name.value == "") {
                // If null display and alert box
                alert("Please fill in the text field.");
                // Place the cursor on the field for revision
                text_form.text_name.focus();
                // return false to stop further processing
                return (false);
            }
           // If text_name is not null continue processing
           if (text_form.text_name.value == "project")
               window.open('project.htm');
           else if (text_form.text_name.value == "under")
               window.open('underconstruction.htm');
           else
               alert("Invalid keyword!");
           return (true);
        }
    -->
    </script>

不确定这是否是一个技巧问题..你不能这样做吗？

<强>脚本

if (text_form.text_name.value == "project")
    document.getElementById('project_link').style.display = 'block';
else if (text_form.text_name.value == "under")
    document.getElementById('construction_link').style.display = 'block';
else
    alert("Invalid keyword!");
return (false);

<强>标记

<a id='project_link' href='project.htm' style='display: none;'>project</a>
<a id='construction_link' href='underconstruction.htm' style='display: none;'>construction</a>

文本框使用if else语句，javascript使链接可见
