Maison > Article > développement back-end > 求js代码能够将用户输入的手机号，验证，并传入后台的代码
前端页面如下
<p class="form-group">
{!! Form::label('phone','新手机号',['class' => 'col-md-2 control-label']) !!}
<p class="col-md-5">
{!! Form::text('phone',null,['class'=>'form-control']) !!}
</p>
<p class="col-md-4">
<p class="form-control-static">
<a href="#">发送验证码</a>
</p>
</p>
</p>
后台发送方法位sendVerifyMessage,对应的路由为domain/send-verify-message
求js代码能够将用户输入的手机号，验证，并传入后台的代码。
回答：
需要jquery 和 jquery.cookie
var SendCode = (function($, Cookies) {
return {
_config : {sendObj:$('#sendCode'), mobile:$('input[name=mobile]')},
_timer : null,
/**
* 初始化发化验证码类
*
*/
init : function(config) {
this._initDisable();
$.extend(this._config, config);
return this;
},
/**
* 异步检查手机号是否合法
*/
AsynCheckMobile : function(url, data, successCallback, errorCallback) {
this.doPost({ url: url, data:data, successCallback:successCallback, errorCallback:errorCallback});
},
/**
* 发送验证码
*/
sendCode : function(url, data, successCallback, errorCallback) {
this.doPost({ url: url, data:data, successCallback:successCallback, errorCallback:errorCallback});
},
/**
* 异步交互动作
*/
doPost : function(params) {
if (toString.call(params.successCallback) !== "[object Function]") {
params.successCallback = function() {};
}
if (toString.call(params.errorCallback) !== "[object Function]") {
params.errorCallback = function() {};
}
var _this = this;
$.ajax({
url : params.url,
data : params.data,
type : 'post',
dataType : 'json',
success : function(result) {
if (result.code == 200) {
params.successCallback.call(_this, result);
} else {
params.errorCallback.call(_this, result);
}
}
})
},
checkMobile: function() {
return /\d{11}/.test(this._config.mobile.val());
},
/**
* 禁用按钮
*/
_disableButton : function() {
var TotalSeconds = 60;
var storeState = Cookies.getJSON('state');
storeState = storeState || {TotalSeconds:TotalSeconds, enable:false};
Cookies.set('state', JSON.stringify(storeState), {path:''});
this._config.sendObj.prop('disabled', true);
var _this = this;
this._timer = setInterval(function() {
var _state = Cookies.getJSON('state');
if (_state.TotalSeconds <= 0) {
clearInterval(_this._timer);
Cookies.remove('state', { path: '' });
_this._config.sendObj.removeAttr('disabled');
_this._config.sendObj.html('发送验证码');
} else {
_this._config.sendObj.html(_state.TotalSeconds + '秒后发送');
_state.TotalSeconds -= 1;
Cookies.set('state', _state, {path:''})
}
}, 1000);
},
_initDisable : function() {
var _state = Cookies.getJSON('state');
if (_state) {
this._disableButton();
}
}
}
})(jQuery, Cookies);
var AsynV = {
'asynValidateCode' : function(data, successCallback, errorCallback) {
data = data || { code:$('input[name=captcha]').val()};
successCallback = successCallback || function() { return true;};
errorCallback = errorCallback || function() {return false;};
$.post('/simple/_asyn_check_code', data, function(result) {
if (200 == result.code) {
(successCallback)();
} else {
(errorCallback)();
}
}, 'json');
}
};
SendCode.init();
$('#sendCode').bind('click', function() {
var captcha = $('input[name=captcha]').val();
if (captcha != '') {
AsynV.asynValidateCode({ code:captcha}, function() {
if (SendCode.checkMobile()) {
SendCode.sendCode('/simple/_send_mobile_validate_code', { mobile:SendCode._config.mobile.val()}, function(result) {
alert(result.message);
this._disableButton();
}, function(result) {
alert(result.message);
});
} else {
alert('不正确的手机号');
}
}, function() {
alert('图形验证码不正确');
});
} else {
alert('请先输入图形验证码');
}
}); HTML:
<p class="form-group">
{!! Form::label('phone','新手机号',['class' => 'col-md-2 control-label']) !!}
<p class="col-md-5">
{!! Form::text('phone',null,['class'=>'form-control']) !!}
</p>
<p class="col-md-4">
<p class="form-control-static">
<a id="send-captcha" href="#">发送验证码</a>
</p>
</p>
</p>
JS:
<script>
// 定义按钮btn
var btn = $("#send-captcha");
// 定义发送时间间隔(s)
var SEND_INTERVAL = 60;
var timeLeft = SEND_INTERVAL;
/**
* 绑定btn按钮的监听事件
*/
var bindBtn = function(){
btn.click(function(){
// 需要先禁用按钮（为防止用户重复点击）
btn.unbind('click');
btn.attr('disabled', 'disabled');
$.ajax({
// ajax接口调用...
})
.done(function () {
alert('发送成功');
//成功
timeLeft = SEND_INTERVAL;
timeCount();
})
.fail(function () {
//失败，弹窗
alert('发送失败');
// ** 重要：因为发送失败，所以要恢复发送按钮的监听 **
bindBtn();
btn.remove('disabled');
});
})
}
/**
* 重新发送计时
**/
var timeCount = function() {
window.setTimeout(function() {
if(timeLeft > 0) {
timeLeft -= 1;
btn.html(timeLeft + "后重新发送");
timeCount();
} else {
btn.html("重新发送");
bindBtn();
}
}, 1000);
}
</script>
