巧用weui.topTips验证数据
场景一、有一个输入金额的场景,这个金额需要验证,验证说明如下:
不能为空格;
不能为0;
不能为汉字;
不能为其它字符;
不能大于200;
唯一可以的是,只有输入3~199之间的数字,下面的确定按钮才会显示,否则,隐藏这个按钮。
HTML:
<!--医生问诊金额--> <div class="weui-jiaj-panel"> <div class="weui-jiaj-money-box dialog js_show"> <div class="weui-jiaj-money-box-btn"> </div> <div class="weui-jiaj-money-box-three"> <div class="weui-flex__item"> <a id="showMoney" href="javascript:;" class="weui-btn weui-btn_mini weui-btn_default">其它</a> </div> </div> </div> </div> <!--其它金额--> <div class="weui_dialog_alert" id="showMoneyDialog" style="display: none;"> <div class="weui_mask"></div> <div class="weui_dialog"> <div class="weui_dialog_hd"><strong class="weui_dialog_title">其它金额</strong></div> <div class="weui_dialog_bd"> <div class="weui-jiaj-dialog-panel"> <div class="weui-cell"> <div class="weui-cell__bd"> <input id="dialogPrice" type="text" required class="weui-input" placeholder="¥10" /> </div> </div> </div> </div> <div class="weui_dialog_ft"> <div id="otherPriceBtn" class="weui_btn_dialog primary">确定</div> </div> </div> </div>
JS:
<script> //设置其它金额 var doctorPrices = [{ "doctorPrice": "5" }, { "doctorPrice": "10" }, { "doctorPrice": "15" }, { "doctorPrice": "20" }, { "doctorPrice": "30" }, { "doctorPrice": "60" }]; var userId = $.cookie('doctorId'); $(function() { selectedPrice(); }); var page = $('.page'); //顶层div var panel = page.find('weui-jiaj-panel'); function selectedPrice() { var $titleHtml = ''; for(var a = 0; a < doctorPrices.length; a++) { var priceName = doctorPrices[a].doctorPrice; //点周weui_btn_dialog隐藏 $titleHtml += '<button class="price_btn weui-btn weui-btn_mini weui-btn_warn"' + 'name=' + priceName + '>' + priceName + '</button>'; $('.price_btn').css('margin', '5px'); } $('.weui-jiaj-money-box-btn').append($titleHtml); //选择金额 $('.price_btn').click(function() { var titleValue = $(this).attr('name'); //$(this)表示获取当前被点击元素的name值 var data = { userId: userId, price: titleValue }; data = JSON.stringify(data); $.ajax({ data: {}, dataType: 'json', type: "post", url: postDoctorPrice().replace("{userId}", userId).replace("{price}", titleValue), contentType: 'application/json; charset=utf-8', success: function(data) { if(data && data.status == '200') { weui.topTips('提交成功'); } }, error: function(data) { location.href = 'doctor_wode.html'; } }); }); //其它金额 $('#otherPriceBtn').on('click', function(e) { var otherPrice = $('#dialogPrice').val(); otherPrice = parseInt(otherPrice); otherPrice = otherPrice.toString(); console.log("其它金额" + otherPrice); var data = { userId: userId, price: otherPrice }; data = JSON.stringify(data); $.ajax({ data: {}, dataType: 'json', type: "post", url: postDoctorPrice().replace("{userId}", userId).replace("{price}", otherPrice), //post 时url带参数 contentType: 'application/json; charset=utf-8', success: function(data) { if(data && data.status == '200') { weui.topTips('设置成功!'); } }, error: function(data) { location.href = 'doctor_wode.html'; } }); }); } //验证 $('input').on('blur',function(){ var value = this.value; var regChinese = new RegExp("[\\u4E00-\\u9FFF]+","g"); //字符串不能为空 if(value.length == 0) { $('#otherPriceBtn').hide(); weui.topTips('不能为空'); //字符串是否为“空”字符即用户输入了空格 }else if(value.replace(/(^s*)|(s*$)/g, "").length ==0){ $('#otherPriceBtn').hide(); weui.topTips('不能为空'); //字符串是否为空或者全部都是空格 }else if(value == null){ $('#otherPriceBtn').hide(); weui.topTips('不能为null'); //字符串是否为汉字 }else if(regChinese.test(value)){ $('#otherPriceBtn').hide(); weui.topTips('不能输入汉字'); //字符串不能为0 }else if(parseInt(value) == 0){ $('#otherPriceBtn').hide(); weui.topTips('不能为0'); //不能大于200 }else if(parseInt(value) > 200){ $('#otherPriceBtn').hide(); weui.topTips('自定义金额不能大于200元'); //自定义金额只能是数字 }else if(typeof(parseInt(value))){ $('#otherPriceBtn').show(); } }) </script>
场景二、所有违反规距的都有信息提示,但是“确定”按钮不隐藏,只是删除它的click事件,只有符合条件的才可以跳转
//验证 $('input').on('blur', function() { var value = this.value; var regChinese = new RegExp("[\\u4E00-\\u9FFF]+", "g"); //汉语 var specialSymbol =/[`~!@#$%^&*_+<>{}\/'[\]]/im; //特殊符号 //字符串不能为空 if(value.length == 0) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('不能为空,请重新输入'); }, 500); //字符串是否为“空”字符即用户输入了空格 } else if(value.replace(/(^s*)|(s*$)/g, "").length == 0) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('不能为空,请重新输入'); }, 500); //字符串是否为空或者全部都是空格 } else if(value == null) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('不能为空,请重新输入'); }, 500); //字符串是否为汉字 } else if(regChinese.test(value)) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('不能输入汉字,请重新输入'); }, 500); //字符串不能为0 } else if(parseInt(value) == 0) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('不能为0,请重新输入'); }, 500); //小于3 } else if(parseInt(value) < 4) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('自定义金额不能小于3,请重新输入'); }, 500); //不能大于200 } else if(parseInt(value) > 200) { $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('自定义金额不能大于200,请重新输入'); }, 500); } else if(specialSymbol.test(value)){ //禁止输入特殊字符 $('#otherPriceBtn').unbind('click'); setTimeout(function() { $('.hide-description').css('display', 'block').text('不可输入!@#¥%……&*特殊字符!'); }, 500); //自定义金额只能是数字 } else if(typeof(parseInt(value))) { setTimeout(function() { $('.hide-description').css('display', 'block').text('你设置的金额为' + value); }, 500); //其它金额 $('#otherPriceBtn').on('click', function(e) { var otherPrice = $('#dialogPrice').val(); otherPrice = parseInt(otherPrice); otherPrice = otherPrice.toString(); console.log("其它金额" + otherPrice); var data = { userId: userId, price: otherPrice }; data = JSON.stringify(data); $.ajax({ data: {}, dataType: 'json', type: "post", url: postDoctorPrice().replace("{userId}", userId).replace("{price}", otherPrice), //post 时url带参数 contentType: 'application/json; charset=utf-8', success: function(data) { if(data && data.status == '200') { weui.topTips('设置成功!'); } }, error: function(data) { location.href = 'doctor_wode.html'; } }); }); } })
