p5.js |加入()函数

p5.js 中的join()函数用于使用分隔符将输入的字符串数组连接成单个字符串。这个分隔符可能是任何字符,它们的位置位于输入数组的两个字符串之间。

句法:

join(Array, Separator)

参数:该函数接受上面提到的两个参数,如下所述:

  • 数组:这是要连接的字符串数组。
  • 分隔符:这是要放置在输入数组的两个字符串之间的任何字符。

返回值:它返回连接的字符串。

下面的程序说明了 p5.js 中的 join()函数:

示例 1:此示例使用 join()函数连接输入数组元素。

function setup() { 
   
    // Creating Canvas size
    createCanvas(450, 120); 
} 
   
function draw() { 
       
    // Set the background color 
    background(220); 
     
    // Initializing the Array of strings
    let Array1 = ["Geeks", "for", "Geeks"];
    let Array2 = ["1", "2", "3"];
    let Array3 = ["a", "A", "b", "B"];
     
    // Initializing the separator character
    let Separator1 = "/";
    let Separator2 = "&";
    let Separator3 = "*";
           
     
    // Calling to join() function.
    let A = join(Array1, Separator1);
    let B = join(Array2, Separator2);
    let C = join(Array3, Separator3);
           
    // Set the size of text 
    textSize(16); 
       
    // Set the text color 
    fill(color('red')); 
     
    // Getting joined strings
    text("Joined string is: " + A, 50, 30);
    text("Joined string is: " + B, 50, 60);
    text("Joined string is: " + C, 50, 90);
        
} 

输出:

function draw() { 
       
    // Set the background color 
    background(220);
           
    // Calling join() function over the parameter
    // Array of strings and separator
    let A = join(["kolkata", "Mumbai", "Delhi"], " ");
    let B = join(["Geeks", "for", "Geeks"], "");
    let C = join(["Ram", "Shyam", "Geeks", "Rahim"], "+");
           
    // Set the size of text 
    textSize(16); 
       
    // Set the text color 
    fill(color('red')); 
     
    // Getting joined strings
    text("Joined string is: " + A, 50, 30);
    text("Joined string is: " + B, 50, 60);
    text("Joined string is: " + C, 50, 90);
} 

输出:
