Question

尝试将div内容从模板div（o_time_templ）复制到另一个并替换其中的两个单词。在更改选择时，应复制内容，将其放入＆＃39; o_time_mss＆＃39;并替换更改1和2.

我的代码如下。第一次克隆后，克隆内容为空。

＆＃13;

$('select[id=o_time]').on('change', function() {
  var template = $("#o_time_templ p").clone().html();

  var delTimeVars = $('#o_time').val();
  delTimeVars = delTimeVars.split('-');
  var delTime = delTimeVars[0];
  var delTime_price = delTimeVars[1];

  if (delTime_price != undefined) {
    $("#o_time_mss").replaceWith(template);
    $("#o_time_mss p").text($("#o_time_mss p").text().replace("o_time_zone_screen", delTime).replace("o_time_price_screen", delTime_price));
    $("#o_time_mss").show();
  }
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="form-control" name="o_time" id="o_time" required>
  <option value="">Delivery time</option>
  <option value="Normal lunch">Normal lunch</option>
  <option value="Breakfast-20">Breakfast</option>
  <option value="After 5pm-40">After 5pm)</option>
  <option value="Saturday-120">Saturday</option>
  <option value="Sunday-120">Sunday</option>
</select>
<div class="hidden" id="o_time_mss">
  <p>change 1: o_time_zone_screen AND change 2: o_time_price_screen</p>
</div>
<div class="hidden" id="o_time_templ">
  <p>change 1: o_time_zone_screen AND change 2: o_time_price_screen</p>
</div>

不要用模板替换o_time_mss，因为它会用文本替换所有html内容。使用html（）

// Angular App Code
var app = angular.module('myApp', ['offClick']);

app.controller('myAppController', ['$scope', '$timeout', function($scope,$timeout) {
  $scope.showContainer = false;
  
  $scope.toggleContainer = function() {
    $timeout(function() {
      $scope.showContainer = !$scope.showContainer;
    }, 300);
    
  };
  
  $scope.hideContainer = function(scope, event, p) {
    $scope.showContainer = false;
    console.log('event: ', event);
    console.log('scope: ', scope);
    console.log(p);
  };
}]);

// Off Click Directive Code
angular.module('offClick', [])
    .directive('offClick', ['$rootScope', '$parse', function ($rootScope, $parse) {
    var id = 0;
    var listeners = {};
    // add variable to detect touch users moving..
    var touchMove = false;

    // Add event listeners to handle various events. Destop will ignore touch events
    document.addEventListener("touchmove", offClickEventHandler, true);
    document.addEventListener("touchend", offClickEventHandler, true);
    document.addEventListener('click', offClickEventHandler, true);

    function targetInFilter(target, elms) {
        if (!target || !elms) return false;
        var elmsLen = elms.length;
        for (var i = 0; i < elmsLen; ++i) {
            var currentElem = elms[i];
            var containsTarget = false;
            try {
                containsTarget = currentElem.contains(target);
            } catch (e) {
                // If the node is not an Element (e.g., an SVGElement) node.contains() throws Exception in IE,
                // see https://connect.microsoft.com/IE/feedback/details/780874/node-contains-is-incorrect
                // In this case we use compareDocumentPosition() instead.
                if (typeof currentElem.compareDocumentPosition !== 'undefined') {
                    containsTarget = currentElem === target || Boolean(currentElem.compareDocumentPosition(target) & 16);
                }
            }

            if (containsTarget) {

        if( event.type === 'touchmove' ){
            touchMove = true;
            // And end function
            return false;
        }

        if( touchMove ){
            // Reset touchmove to false
            touchMove = false;

            return false;
