angularjs ng-switch-when 输入字段的值

Question

如何将这两个输入字段合并为一个，并根据 ng-switch-when 值切换它们的值？

<div class="form-group">
    <label ng-switch="mymodel.toggle" class="pull-left">
        <input type="text"  value="Option A" ng-switch-when="true" disabled="disabled" />
        <input type="text" value="Option B" ng-switch-when="false" disabled="disabled" />
    </label>
    <switch class="pull-right checkbox" ng-model="mymodel.toggle" ng-init="mymodel.toggle= true" class="green"></switch>
</div>

我的意思是，如果为真，则显示 "Option A" 作为值，如果不显示 "Option B" 作为值，所有这些都在一个输入字段中。

更新：

问题是当点击切换开关时，新的输入框出现在旧的输入框旁边一秒钟然后消失，这太丑陋了。我正在寻找解决这个问题的方法。

Answer 1

尝试使用

<div ng-switch="your_boolean_variable">
    <input type="text"  value="Option A" ng-switch-when="true"
            disabled="disabled"/>
    <input type="text" value="Option B" ng-switch-when="false"
            disabled="disabled"/>
</div>

其中 ng-switch 是您的控制器中定义的变量。根据该变量是否为真，您应该看到 Option A，如果为假，您应该看到 Option B

或者您也可以使用 ng-if 之类的

<input type="text"  value="Option A" ng-if="your_boolean_variable == true"
        disabled="disabled"/>
<input type="text" value="Option B" ng-if="your_boolean_variable == false"
        disabled="disabled"/>

我认为问题出在您的 switch 指令中。据我了解，您的代码工作正常：s

angular.module("uiSwitch", []).directive("switch", function() {
  return {
    restrict: "AE",
    replace: !0,
    transclude: !0,
    template: function(n, e) {
      var s = "";
      return s += "<span", s += ' class="switch' + (e.class ? " " + e.class : "") + '"', s += e.ngModel ? ' ng-click="' + e.ngModel + "=!" + e.ngModel + (e.ngChange ? "; " + e.ngChange + '()"' : '"') : "", s += ' ng-class="{ checked:' + e.ngModel + ' }"', s += ">", s += "<small></small>", s += '<input type="checkbox"', s += e.id ? ' id="' + e.id + '"' : "", s += e.name ? ' name="' + e.name + '"' : "", s += e.ngModel ? ' ng-model="' + e.ngModel + '"' : "", s += ' style="display:none" />', s += '<span class="switch-text">', s += e.on ? '<span class="on">' + e.on + "</span>" : "", s += e.off ? '<span class="off">' + e.off + "</span>" : " ", s += "</span>"
    }
  }
});

var app = angular.module('testApp', ["uiSwitch"]);

app.controller('testController', function($scope) {

});

.switch {
  background: #fff;
  border: 1px solid #dfdfdf;
  position: relative;
  display: inline-block;
  box-sizing: content-box;
  overflow: visible;
  width: 52px;
  height: 30px;
  padding: 0px;
  margin: 0px;
  border-radius: 20px;
  cursor: pointer;
  box-shadow: rgb(223, 223, 223) 0px 0px 0px 0px inset;
  transition: 0.3s ease-out all;
  -webkit-transition: 0.3s ease-out all;
  top: -1px;
}
/*adding a wide width for larger switch text*/

.switch.wide {
  width: 80px;
}
.switch small {
  background: #fff;
  border-radius: 100%;
  box-shadow: 0 1px 3px rgba(0, 0, 0, 0.4);
  width: 30px;
  height: 30px;
  position: absolute;
  top: 0px;
  left: 0px;
  transition: 0.3s ease-out all;
  -webkit-transition: 0.3s ease-out all;
}
.switch.checked {
  background: rgb(100, 189, 99);
  border-color: rgb(100, 189, 99);
}
.switch.checked small {
  left: 22px;
}
/*wider switch text moves small further to the right*/

.switch.wide.checked small {
  left: 52px;
}
/*styles for switch-text*/

.switch .switch-text {
  font-family: Arial, Helvetica, sans-serif;
  font-size: 13px;
}
.switch .off {
  display: block;
  position: absolute;
  right: 10%;
  top: 25%;
  z-index: 0;
  color: #A9A9A9;
}
.switch .on {
  display: none;
  z-index: 0;
  color: #fff;
  position: absolute;
  top: 25%;
  left: 9%;
}
.switch.checked .off {
  display: none;
}
.switch.checked .on {
  display: block;
}

在我看来，永远不需要 ng-switch。 ng-if 好多了。

    <label ng-if="mymodel.toggle" class="pull-left">
        <input type="text"  value="Option A" ng-switch-when="true" disabled="disabled" />
    </label>
    <label ng-if="!mymodel.toggle" class="pull-left">
        <input type="text" value="Option B" ng-switch-when="false" disabled="disabled" />
    </label>
