我用欧芹验证包制作了两步表格。
这是html:
<form action="#" method="POST" autocomplete="off" class="enter-form" data-parsley-validate="" data-parsley-focus="first">
<div class="form-group form-section">
<label for="email"><b>email or phone number:</b></label>
<input type="text" title="enter email or phone number" autofocus="autofocus" tabindex="1" class="form-control" id="email" required="" data-parsley-emailorid="" />
</div>
<div class="form-group form-section">
<label for="pwd"><b>password:</b></label>
<input type="password" title="enter password" tabindex="2" class="form-control" id="pwd" required="" />
</div>
<div class="form-navigation">
<button type="button" class="previous btn btn-primary pull-left">
previous >
</button>
<button type="button" class="next btn btn-primary pull-right" id="nextBtn">
< next
</button>
<button type="submit" class="btn btn-rang pull-right">
enter
</button>
<span class="clearfix"></span>
</div>
</form>
这是用于多步骤验证的Java脚本:
$(document).ready(function () {
var $sections = $('.form-section');
function navigateTo(index) {
$sections
.removeClass('current')
.eq(index)
.addClass('current');
$('.form-navigation .previous').toggle(index > 0);
var atTheEnd = index >= $sections.length - 1;
$('.form-navigation .next').toggle(!atTheEnd);
$('.form-navigation [type=submit]').toggle(atTheEnd);
}
function curIndex() {
return $sections.index($sections.filter('.current'));
}
$('.form-navigation .previous').click(function() {
navigateTo(curIndex() - 1);
});
$('.form-navigation .next').click(function() {
$('.enter-form').parsley().whenValidate({
group: 'block-' + curIndex()
}).done(function() {
navigateTo(curIndex() + 1);
});
});
$sections.each(function(index, section) {
$(section).find(':input').attr('data-parsley-group', 'block-' + index);
});
navigateTo(0);
});
$(document).ready(function () {
var dummyEmail = $('<input data-parsley-type="email">').parsley();
var dummyDigits = $('<input data-parsley-pattern="\[0-9]{11}">').parsley();
window.Parsley.addValidator('emailorid', {
validateString: function(data) {
return dummyDigits.isValid(true, data) || dummyEmail.isValid(true, data);
},
messages: {
en: "Is neither a nine digit long number nor a valid email address"
}
});
});
在第一步中,我无法使用“ enter”键进入下一步。因此,我编写了以下代码来触发“输入”键上的“ #nextBtn”:
$(document).ready(function () {
var input = document.getElementById("email");
input.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
document.getElementById("nextBtn").click();
}
});
});
但是我现在有一个问题。当我使用“ enter”键进入下一步时,它并不专注于密码输入。 我的问题是:使用“ enter”键进入下一步时,如何专注于密码输入?
答案 0 :(得分:1)
您可以通过以下方式输入密码:
document.getElementById("pwd").focus();
或使用jQuery:
$('#pwd).focus();
因此,当您的JavaScript代码在按下Enter键时检测到时,只需将html元素聚焦,然后使用.focus()
函数即可。
