[英]making multiple links visible javascript
一次可以看到多个链接吗? 我的意思是在我的以下代码中,当我在文本字段中输入project
并按提交按钮时, abc.htm
链接变为可见。 现在,我希望在文本字段中输入project
并按提交按钮abc.htm
和xyz.htm
和cold.htm
链接时可见。 在文本字段下书写时也是如此。
<html>
<head>
<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")
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);
}
-->
</script>
</head>
<body>
<form name="text_form" method="get" action="#"
onsubmit="return Blank_TextField_Validator()">
<a id='project_link' href='abc.htm' style='display: none;'>project</a>
<a id='construction_link' href='New Text Document (3).htm' style='display: none;'>construction</a>
<input type="text" name="text_name" >
<input type="submit" value="Submit">
</form>
</body>
</html>
这是我尝试过的:
if (text_form.text_name.value == "project")
document.getElementById('project_link').style.display = 'block';
document.getElementById('project_link_1').style.display = 'block';
<form name="text_form" method="get" action="#" onsubmit="return Blank_TextField_Validator()">
<a id='project_link' href='abc.htm' style='display: none;'>project</a>
<a id='project_link_1' href='xyz.htm' style='display: none;'>projects</a>
<a id='construction_link' href='New Text Document (3).htm' style='display: none;'>construction</a>
更改
if (text_form.text_name.value == "project")
document.getElementById('project_link').style.display = 'block';
document.getElementById('project_link_1').style.display = 'block';
至
if (text_form.text_name.value == "project") {
document.getElementById('project_link').style.display = 'block';
document.getElementById('project_link_1').style.display = 'block';
}
