如何取与 fields[m].validationMessage 相邻元素label.innerhtml的值
<style>
.oneline {
line-height: 1.5;
margin: 10px auto;
}
.oneline label {
width: 100px;
text-indent: 15px;
font-size: 14px;
font-family: "Microsoft Yahei";
display: inline-block;
}
.oneline .sinput {
width: 60%;
height: 30px;
border-radius: 6px;
border: 1px solid #e2e2e2;
}
.oneline input[type="submit"] {
margin-left: 20px;
width: 80px;
height: 30px;
border: 0;
background-color: #5899d0;
color: #fff;
font-size: 14px;
border-radius: 6px;
}
.error-messages {
color: red;
}
</style>
<body>
<form id="forms">
<div class="oneline">
<label for="name">用户名:</label>
<input id="name" class="sinput" name="name" type="text" required>
</div>
<div class="oneline">
<label for="email">Email:</label>
<input id="email" class="sinput" name="email" type="email" required>
</div>
<div class="oneline">
<input type="submit" id="submits" value="提交">
</div>
</form>
<script>
function replaceValidationUI(form) {
form.addEventListener("invalid", function(event) {
event.preventDefault();
}, true);
form.addEventListener("submit", function(event) {
if (!this.checkValidity()) {
event.preventDefault();
}
},true);
//此处写代码
var submits = document.getElementById('submits'),
label = document.getElementsByTagName('label');
submits.addEventListener('click',function(event){
var fields = form.querySelectorAll(':invalid'),
error = form.querySelectorAll('.error-messages'),
parent;
for(var i = 0;i<error.length;i++){
error[i].parentNode.removeChild(error[i]);
};
for(var m = 0;m<label.length;m++){
parent = label[m].parentNode.parentNode;
parent.insertAdjacentHTML("afterBegin","<div class='error-messages'><ul><li>"+label[m].innerText+fields[m].validationMessage+"</li></ul></div>");
};
if (fields.length > 0) {
fields[0].focus();
};
},true)
}
var forms = document.getElementById("forms");
replaceValidationUI(forms);
</script>
</body>
谁能告诉我，如何取与 fields[m].validationMessage 相邻元素label.innerhtml的值； 想不通，弄了 一下午，是不是脑子不好使。。。 还是不需要取这个label值？
