我写了一个简单的注册网页，想确认密码和检查邮箱地址格式，并在同一行输入元素后显示勾号或叉号。
在我将 Bootstrap 添加到我的 html 文件之前，勾号或叉号出现在同一行中的输入元素之后。但是在我将 Bootstrap 添加到我的 html 文件之后(尤其是在添加 class="form-control" 之后)，勾号或叉号反而出现在下一行。
我想知道如何解决我的问题？谢谢。
这是我的 html 文件:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

这是我的javascript
function arePasswordsSame() {
input = this; // document.getElementById("passwordConfirm");
if (input.value != document.getElementById("password").value) {
input.setCustomValidity("Password Must be Matching.");
document.getElementById("passwordConfirmResult").innerHTML = "×";
} else {
input.setCustomValidity("");
document.getElementById("passwordConfirmResult").innerHTML = "✔";
}
}
document.getElementById("passwordConfirm").addEventListener("change",arePasswordsSame);
function validateEmail(){
input = this; // document.getElementById("email");
var mailformat = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
if(! input.value.match(mailformat)){
input.setCustomValidity("Email is invalid.");
document.getElementById("emailResult").innerHTML = "×";
}else{
input.setCustomValidity("");
document.getElementById("emailResult").innerHTML = "✔";
}
}
document.getElementById("email").addEventListener("change",validateEmail);
最佳答案
您可以使用 bootstrap 附带的内置 input-group-addon
<div class="input-group">
<div class="col-lg-5">
<input type="password" class="form-control" name="password" id="password" placeholder="Password" style="border-color: grey; background-color: white">
<span width="5" class="input-group-addon" name="passwordResult" id="passwordResult"></span>
</div>
</div>

这应该是标记；
<div class="form-group">
<div class="col-lg-5">
<div class="input-group">
<input type="password" class="form-control" name="password" id="password" placeholder="Password" style="border-color: grey; background-color: white">
<span class="input-group-addon" name="passwordResult" id="passwordResult"> </span>
</div>
</div>
</div>
