我的问题是 text3 在我这里的代码中未定义:
t += text2 + "Case #" + i + ":" + "<br>" + text3 + "<br>";
但它在这里:
$('#pass').keyup(function (e) {
var strong = new RegExp("^(?=.{11,})(((?=.*[A-Z])(?=.*[a-z])(?=.*[0-9])(?=.*\\W))|((?=.*[A-Z])(?=.*[a-z])(?=.*\\W))|((?=.*[a-z])(?=.*[0-9])(?=.*\\W))|((?=.*[A-Z])(?=.*[0-9])(?=.*\\W))|((?=.*[A-Z])(?=.*[a-z])(?=.*[0-9]))).*$", "g");
var normal = new RegExp("^(?=.{4,})(((?=.*[A-Z])(?=.*[a-z]))|((?=.*[A-Z])(?=.*[0-9]))|((?=.*[a-z])(?=.*[0-9]))|((?=.*[a-z])(?=.*\\W))|((?=.*[0-9])(?=.*\\W))).*$", "g");
if (strong.test($(this).val())) {
text3 = "strong";
} else if (normal.test($(this).val())) {
text3 = "normal";
} else {
text3 = "weak";
}
return true;
});
这是我所有的代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<p><input placeholder="number of tests" type="text" name="numbers" id="x"/></p>
<div id="passdiv"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$('#x').keyup(function (e) {
var i;
var text2 = '';
var t = "";
var x = document.getElementById("x").value;
for (i = 1; i <= x; i++) {
text2 = '<p><input placeholder="test NO. ' + i + '" type="password" id="pass" /></p>';
t += text2 + "Case #" + i + ":" + "<br>" + text3 + "<br>";
}
document.getElementById("passdiv").innerHTML = t;
return true;
});
$('#pass').keyup(function (e) {
var strong = new RegExp("^(?=.{11,})(((?=.*[A-Z])(?=.*[a-z])(?=.*[0-9])(?=.*\\W))|((?=.*[A-Z])(?=.*[a-z])(?=.*\\W))|((?=.*[a-z])(?=.*[0-9])(?=.*\\W))|((?=.*[A-Z])(?=.*[0-9])(?=.*\\W))|((?=.*[A-Z])(?=.*[a-z])(?=.*[0-9]))).*$", "g");
var normal = new RegExp("^(?=.{4,})(((?=.*[A-Z])(?=.*[a-z]))|((?=.*[A-Z])(?=.*[0-9]))|((?=.*[a-z])(?=.*[0-9]))|((?=.*[a-z])(?=.*\\W))|((?=.*[0-9])(?=.*\\W))).*$", "g");
if (strong.test($(this).val())) {
text3 = "strong";
} else if (normal.test($(this).val())) {
text3 = "normal";
} else {
text3 = "weak";
}
return true;
});
</script>
</body>
</html>
问题是什么？ 请帮忙
最佳答案
看起来 $('#x').keyup() 在 $('#pass').keyup() 之前被调用
关于javascript - 函数在我的代码中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26186636/
