【问题描述】:
我有一个字段集,要求用户输入一些数据,例如姓名、电子邮件和电话号码,如下所示:
<h2 class="fs-title">Personal data</h2>
<input type="text" name="firstname" id="firstname" placeholder="First Name" class="textbox" ng-model="firstName"required/>
<input type="text" name="lastname" id="lastname" placeholder="Last Name" class="textbox" ng-model="lastName" required/>
<input type="email" name="email" class="textbox" placeholder="Email" ng-model="user.email" required>
<input type="text" name="contact" placeholder="Phone number" id="contact" ng-model="phoneNumber" required/>
<input type="button" name="next" class="next action-button" value="Next"/>
next 类有一个与之关联的函数:
var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches
$(".next").click(function(){
if(animating) return false;
animating = true;
current_fs = $(this).parent();
next_fs = $(this).parent().next();
//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");
//show the next fieldset
next_fs.show();
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 - stored in "now"
//1. scale current_fs down to 80%
scale = 1 - (1 - now) * 0.2;
//2. bring next_fs from the right(50%)
left = (now * 50)+"%";
//3. increase opacity of next_fs to 1 as it moves in
opacity = 1 - now;
current_fs.css({
'transform': 'scale('+scale+')',
'position': 'absolute'
});
next_fs.css({'left': left, 'opacity': opacity});
},
duration: 800,
complete: function(){
current_fs.hide();
animating = false;
},
//this comes from the custom easing plugin
// easing: 'easeInOutBack'
linear: 'easeInOutBack'
});
});
在当前状态下,即使表单没有正确填写,您也可以单击“下一步”,即使它是空的,我不希望这样。我想在单击下一步时检查输入是否正确填写,如果没有,则在每个字段下显示一条消息/警告,说明问题所在(即在电子邮件中,它必须包含@)
我尝试使用引导程序中的 btn btn-primary 类,但如果我使用它们(它们按照我的意愿进行验证),我将无法再使用我的下一个类。任何想法如何使它工作? 我尝试了 Angular 指令,例如 ng-disable,条件是这些字段为空,但由于某种原因,如果我填写这些字段,按钮仍然不起作用,所以我如何使用 btn btn-primary 并且仍然有我的下一节课?
