我基本上做的是下一个: HTML / PHP表单:
<html>
<head>
<link rel="stylesheet" type="text/css" href="gstyle.css">
</head>
<body>
<script type="text/javascript" src="resources/jquery-1.11.2.min.js"></script>
<script type="text/javascript" src="resources/jquery-ui/jquery-ui.min.js"></script>
<script type="text/javascript" src="script.js"></script>
<form method="POST">
<table border=0>
<tr>
<td class="descripcion">Usuario:</td>
<td><input class="campos" type="text" name="user" placeholder="Nombre de usuario"></td>
</tr>
<tr>
<td class="descripcion">Contraseña:
<td><input class="campos" type="password" name="passwd" placeholder="Contraseña"></td>
</tr>
<tr>
<td class="descripcion">Confirmar contraseña:</td>
<td><input class="campos" type="password" name="confpasswd" placeholder="Confirmar Contraseña"></td>
</tr>
<tr>
<td class="descripcion">Correo:</td>
<td><input class="campos" type="text" name="correo" placeholder="E-Mail"></td>
</tr>
<tr>
<td class="descripcion">Confirmar correo:</td>
<td><input class="campos" type="text" name="confcorreo" placeholder="Confirmar E-Mail"></td>
</tr>
</table>
<br>
<input class="botones" type="submit" name="send" value="Registrar">
</form>
</div>
</body>
</html>
是一个简单的regiter处方集,带有CSS类。 然后我有一个CSS表格,其中包含当前样式以及为JQuery准备的正确和错误的类:
#form {

}
$(document).ready(function(){
var user = $("input[name=user]").val();
if(user === "Vitama") {
$("input[name=user]").addClass("correcto");
}
});
我说这个脚本会做那件事,但我错了。 请帮助一下,我怎样才能让它充满活力?。
答案 0 :(得分:1)
听起来你正在寻找像jQuery中的.keyup
函数。
它会在输入时评估条件。
我还在“correcto”属性中添加了!important
关键字,因此它们会覆盖:focus
属性。
var user;
$("input[name=user]").keyup(function() {
user = $("input[name=user]").val();
if (user === "Vitama") {
$("input[name=user]").addClass("correcto");
}
});
