Vue button, only call method once values of array/object are checked

for loop in vue methods

vue render function
vue data array

I have a working button that calls a function but I want to add a middle layer where it checks the status value of each item in my listItems array to make sure the status is complete on all before calling the method.

THe button call works fine but I'm still struggling with how to check the status of all and fire the error if they aren't all complete or call the method if they are.

Here's the bulk of the code:

<button class="btn  btn-block" v-on:click="completeItem" type="button" role="button" id="completeItemButton" aria-expanded="false">
        Complete
    </button>

    <p>Must complete all before closing out the item</p>


    vue code:

        export default{

            data() {
                return: {
                    listItems: [
                        {
                        id: 1,
                        status: 'Complete'
                        },
                        {
                        id: 2,
                        status: 'Complete'
                        }
                        {
                        id: 3,
                        status: 'Open'
                        }
                    ]
                }
            },
            methods: {

                completeItem() {
                    //more code upon completion
                }
            }
        }

To see if all items in an array match a condition, you can use every. Here's an example:

completeItem() {
  const areAllComplete = this.listItems.every(item => item.status === 'Complete');
  if (areAllComplete) {
    // TODO
  }
}

Render Functions & JSX, Let's dive into a simple example where a render function would be practical. When you get started with a component that only generates a heading based “​Virtual DOM” is what we call the entire tree of VNodes, built by a tree of Vue components. Same API as `v-bind:class`, accepting either // a string, object, or array of  My respose is correct but after this operation my results array look like: "[object Object],[object Object]" I have also tried to add new elements by push method: vm.results.push(response.data.data); But then, elements are added in new arrays but I want to add objects to existing array. Here is the structure of my response:


You can use Array.prototype.some to return a boolean by checking through the array,

try the below code.

completeItem() {
   if(this.listItems.some(item => item.status === 'Open') { // returns true if ANY item has a status of Open
      //throw error
   } else {
      //continue
   }
}

The reverse approach is to check if every status is 'Complete' using Array.prototype.every

We'll need only one variable, which we'll call seconds , and we'll use buttonDisabled; once a second, we would see that the button disabled property Vue also wraps some array methods such as .splice() on observed arrays with​  Don’t use non-primitive values like objects and arrays as v-for keys. Use string or numeric values instead. For detailed usage of the key attribute, please see the key API documentation. Array Change Detection Mutation Methods. Vue wraps an observed array’s mutation methods so they will also trigger view updates. The wrapped methods are


Here:

  completeItem() {
                for(let i=0; i < listItems.length; i++)
                     if(this.listItems[i].status == "Open"){
                          alert("failed")
                           i = 10;
                  }
            }

3 Anti-Patterns to avoid in Vue.js, If you find yourself calling other methods or assigning other properties inside to debug or trace because it requires a “special customer” which may appear only once in a property in a prop that is an object or an array, because it's “Easy” to do so. Dropdown.vue (parent) <template> <div> <button @click="showMenu = ! App.vue < Shop-Item.vue < Shop-Button-Add.vue. Shop-Button-Add.vue is nested inside of Shop-Item.vue, which is nested inside of App.vue. What we need to do here is figure out a way to emit an event from Shop-Button-Add.vue up to Shop-Item.vue, which then triggers an emit event from Shop-Item.vue up to App.vue. Sounds a bit complicated, but it's


Iterating Over Items in Vue.js With V-for, A quick breakdown of V-for and its usage in Vue.js. This will output an unordered list with the values from the array. Similarly, we can loop over the objects in the shoppingItems array. Here we can access the values using The v​-for directive only applies to the element that it's attached to. If multiple items  To make the Button component useful, we need to add the option to pass in a click event from the parent component. This is done through the use of props. Open Button.vue, so far we've only altered the template. To allow our parent component to send a method to our Button component, we need to define an onClick prop:


How to use computed properties in Vue, Unless you are looking to trigger a function after an event, you There are multiple ways in Vue to set values for the view. Let's check our example code, then we'll explain what is going on: So we first run the map() function on our cart array which returns a new array that just has the prices of each item. Notice that the key names within this object match the names that we specify within the ref attribute, and the values are the DOM elements. In this case, we can see that the key is myButton and that the value is a native button element which has nothing to do with Vue.js.
