Replacing Label With Input Textbox And Vice Versa By Clicking A Button In Angularjs

I have a form with label and button Edit, when I click on button, Label should be converted into textbox with the label data as text and when I save it, textbox should be converted

Solution 1:

You can just show/hide label and inputs using ngshow and ngHide. Basically the <label> should contain an expression displaying the data and corresponding <input> should contain ngModel pointing to same data. Then use the buttons to simply switch between display modes:

angular.module('test', []).controller('testCtrl', function($scope) {
  $scope.editMode = false;
  $scope.name = "John Doe";
});

<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script><divng-app="test"ng-controller="testCtrl"><form><labelng-hide="editMode">{{name}}</label><inputng-show="editMode"ng-model="name"><buttonng-click="editMode=true">Edit</button><buttonng-click="editMode=false">Save</button></form></div>

If you think your form is very heavy and don't want to have both the <label> and <input> in DOM at same time, use ngIf instead.

Solution 2:

You could use the contenteditable attribute in your label tag.

Check this demo:

(function() {
  "use strict";

  var app = angular.module("app", []);
  app.controller("Controller", ["$scope",
    function($scope) {
      $scope.buttonText = "Edit";

      $scope.editSave = function(evt) {
        var label = evt.target.previousElementSibling; // Get the label tag from your button.var labelData = label.innerText; // Get the label text.alert(labelData);

        if ($scope.buttonText == "Edit") { // If the current button's text is "Edit"...
          label.setAttribute("contenteditable", true); // Set contenteditable=true to your label./* To make focusable your editable label. */
          label.setAttribute("target", 0);
          label.focus(); // Set the focus in your label.
          $scope.buttonText = "Save"; // Change the button's text to "Save".
        } else {
          label.removeAttribute("contenteditable");
          label.removeAttribute("target");
          $scope.buttonText = "Edit";
        }
      };
    }
  ]);
})();

label {
  padding: 2px;
}
label[contenteditable=true] {
  border: solid 1px#CCCCCC;
  padding: 2px;
}

<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script><divdata-ng-app="app"><divdata-ng-controller="Controller"><formid="form"><div><label>Label</label><buttondata-ng-bind="buttonText"data-ng-click="editSave($event)"type="button"></button></div></form></div></div>

This demo works with your last update:

(function() {
  angular
    .module("testApp", [])
    .controller('testController', function($scope) {
      $scope.buttonText = "Edit";

      $scope.editLabel = function(evt) {
        var label = evt.target.previousElementSibling; // Get the label tag from your button.var labelData = label.innerText; // Get the label text.alert(labelData);

        if ($scope.buttonText == "Edit") { // If the current button's text is "Edit"...
          label.setAttribute("contenteditable", true); // Set contenteditable=true to your label./* To make focusable your editable label. */
          label.setAttribute("target", 0);
          label.focus(); // Set the focus in your label.
          $scope.buttonText = "Save"; // Change the button's text to "Save".
        } else {
          label.removeAttribute("contenteditable");
          label.removeAttribute("target");
          $scope.buttonText = "Edit";
        }
      };
    });
})();

<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script><formng-app="testApp"ng-controller="testController"><labelclass="keyColumn">name:</label><labelclass="valueCoulmn">stackover flow</label><buttonng-bind="buttonText"ng-click="editLabel($event)"></button></form>

Hope this helps.
