涉及到的樣式修改代碼jquery-weui.css中添加
.toolbar .cancel-picker {  position: absolute;  box-sizing: border-box;  height: 2.2rem;  line-height: 2.2rem;  color: #04BE02;  z-index: 1;  padding: 0 .5rem;}涉及到j(luò)query-weui.js源碼中的修改
toolbarTemplate: '<div class="toolbar">/          <div class="toolbar-inner">/          <a href="javascript:;" class="cancel-picker">取消</a>/          <a href="Javascript:;" class="picker-button close-picker">{{closeText}}</a>/          <h1 class="title">{{title}}</h1>/          </div>/          </div>',添加了<a href="javascript:;" class="cancel-picker">取消</a>/
地區(qū)選擇器默認(rèn)只要改變就實(shí)時(shí)的顯示到文本輸入框中,我的需求是點(diǎn)擊確定才改變值，點(diǎn)擊取消不改變。查看源碼發(fā)現(xiàn)
p.updateValue = function () {          var newValue = [];          var newDisplayValue = [];          for (var i = 0; i < p.cols.length; i++) {              if (!p.cols[i].divider) {                  newValue.push(p.cols[i].value);                  newDisplayValue.push(p.cols[i].displayValue);              }          }          if (newValue.indexOf(undefined) >= 0) {              return;          }          p.value = newValue;          p.displayValue = newDisplayValue;          if (p.params.onChange) {              p.params.onChange(p, p.value, p.displayValue);          }          if (p.input && p.input.length > 0) {              // $(p.input).val(p.params.formatValue ? p.params.formatValue(p, p.value, p.displayValue) : p.value.join(' '));              $(p.input).trigger('change');          }      };注釋掉的就是導(dǎo)致實(shí)時(shí)改變input框的代碼，將其移至確定按鈕點(diǎn)擊時(shí)間代碼中
$(document).on("click", ".close-picker", function() {        var pickerToClose = $('.weui-picker-modal.weui-picker-modal-visible');        if (pickerToClose.length > 0) {          $(p.input).val(p.params.formatValue ? p.params.formatValue(p, p.value, p.displayValue) : p.value.join(' '));          $.closePicker(pickerToClose);        }      });由于取消按鈕是后來(lái)添加的，所以也給其注冊(cè)點(diǎn)擊事件
  $(document).on("click", ".cancel-picker", function() {    var pickerToClose = $('.weui-picker-modal.weui-picker-modal-visible');    if (pickerToClose.length > 0) {      $.closePicker(pickerToClose);    }  });
發(fā)現(xiàn)一個(gè)bug，每次選擇完取消再點(diǎn)擊顯示的是新選擇的值而不是原來(lái)input正確的值，估計(jì)還是因?yàn)槟J(rèn)是實(shí)時(shí)顯示引起的。查看源碼
// Set value              if (!p.initialized) {                  if (p.params.value) {                      p.setValue(p.params.value, 0);                  }              }              else {                  var tmpCode = p.params.toCode(p.params.rawCitiesData, p.input.val());                  p.setValue(tmpCode, 0);                  // if (p.value) p.setValue(p.value, 0);              }注釋部分就是把change引起的新值顯示到控件上，所以只需要改為顯示input中的值。
p.params.toCode和p.params.rawCitiesData在config中配置，具體見city-picker.js
最后展示一下季度選擇器
