I have been working on a game and I need to call a function on the value of the key 'sides' (similar to 'onclick="rollDice(6)"'). I've tried using mustache interpolation and also v-binding, but I cannot seem to return anything other than NaN or undefined.

Relevant markup:

   <v-list>
    <v-list-tile v-for="die in dice" :key="die.name">
      <v-list-tile-avatar>
        <v-avatar size="32px" tile @click="rollDice()" >
          <img :src="die.img">
        </v-avatar>
      </v-list-tile-avatar>
      <v-list-tile-title>{{ die.name }}</v-list-tile-title>
    </v-list-tile>
  </v-list>

From data:

dice: [
    { img: require("../assets/d4.svg"), name: "d4", sides: 4 },
    { img: require("../assets/d6.svg"), name: "d6", sides: 6  },
    { img: require("../assets/d8.svg"), name: "d8", sides: 8 },
  ]

From methods:

  rollDice: function(sides){
  var rollResult = Math.ceil(Math.random() * sides)
  console.log(rollResult)
}

I tried to keep the linked code minimal, but if I can link anything further, I'd be glad to. Thank you in advance for your assistance!

You are not passing die.sides to the click handler like this: @click="rollDice(die.sides)".

Full code will be:

<v-list>
  <v-list-tile v-for="die in dice" :key="die.name">
    <v-list-tile-avatar>
      <v-avatar size="32px" tile @click="rollDice(die.sides)" >
        <img :src="die.img">
      </v-avatar>
    </v-list-tile-avatar>
    <v-list-tile-title>{{ die.name }}</v-list-tile-title>
  </v-list-tile>
</v-list>

Defining and Calling Methods, value1, value2, value3, and so on are the default values of the arguments. The method automatically sets the argument equal to this value if the method is called � If the interface of a method consists only of IMPORTING parameters, you can use the following shortened form of the method call: CALL METHOD method( i 1 = f 1 i 2 = f 2). Each actual parameter f 1 is passed to the corresponding formal parameter i 1. Dynamic Method Call. Using the standard ABAP parenthesis semantics you can call methods dynamically.

So, my issue was a simple one. I made the following change and it seems to be working as expected after making the following changes to the click event:

<v-avatar size="32px" tile @click="rollDice(die.sides)">

If there is a better way this can be done, I'd be interested to see. I am new to Vue, but having a blast with it, but I could definitely stand to learn some best practices!

Parameter Passing Techniques in Java with Examples , There are different ways in which parameter data can be passed into and out of methods and This method is also called as call by value. Call by value is the default method in programming languages like C++, PHP, Visual Basic NET, and C# whereas Call by reference is supported only Java language. Call by Value, variables are passed using a straightforward method whereas Call by Reference, pointers are required to store the address of variables.

 <v-list>
<v-list-tile v-for="(die, index) in dice" :key="die.name">
  <v-list-tile-avatar>
    <v-avatar size="32px" tile @click="rollDice(die.sides)" >
      <img :src="die.img">
    </v-avatar>
  </v-list-tile-avatar>
  <v-list-tile-title>{{ die.name }}</v-list-tile-title>
</v-list-tile>

Key value pairs in C# Params, public static void MyFunction(params (string Key, object Value)[] pairs) Method. GetParameters()[0]).Name; var val = args[0].Invoke(null); var name2 = (args[1]. A method can return native data types (int, float, double, etc), native objects (String, Map, List, etc), or any other built-in and user-defined objects. If the method does not return a value, its return type is void. nameOfMethod - It is an identifier that is used to refer to the particular method in a program. We can give any name to a method.

D3 Key Function, The data() call matched an array of divs with an array of values by use of a key. The default keys used for the arrays is the indexes. So these are the keys that� GET: Used to request data from an endpoint; POST: Sends data to an endpoint; DELETE: Remove data from an endpoint. PATCH: Update a record or data value at an endpoint. These types of interactions are external from the local environment, and therefore, the APIs that are providing the data or services are called external APIs.

CALL METHOD - parameter_tables, The data object pointed to by the reference variable in VALUE is assigned to the formal parameter specified in NAME. The column NAME is the unique key of the � If you want to find the value of a known key, you have to use the Python get () function. The dictionary contains the keys with its associated values. The values in the dictionary variable can be identified by the key. However, if you want to know more about the dictionary, you may like to read Python Dictionary.

.data(), An object of key-value pairs of data to update. The .data() method allows us to attach data of any type to DOM elements in a way Calls such as .data( "name", undefined ) will return the jQuery object that it was called on, allowing for chaining. You should avoid binding to properties that call methods esp if the method could potentially be long running. Having such methods it properties is not good design as a consumer of code expects a property to only access a local variable. – markmnl Dec 15 '10 at 16:52

  • I realized my mistake shortly after posting this, embarrassingly enough. Out of curiosity, is there an advantage to using v-for="(die, index) in dice" :key="die.name" over v-for="die in dice" :key="die.name"? Thanks for your help!
  • when you use for each makes use key is needed to be unique instead of a string you can get index as key and assign in to :key="index" that is standard way forum.vuejs.org/t/v-for-with-simple-arrays-what-key-to-use/…
  • Excellent! I will be sure to do it this way in the future! Thanks again!
