javascript - Calling functions from within functions JS -

-

i'm writing small battleships game, , i'm refactoring code using javascript objects, tool not familiar with. able call function within function using objects, , cannot seem work out how this. code here:

<script> var xpos; var ypos; var boatgrid = {      selectpos : function() {         console.log("it works"); //want try calling function addnumber() here         (boatnum = 1; boatnum < 4; boatnum++) {             xpos = math.floor(math.random() * 8);             ypos = math.floor(math.random() * 10 + 1);         }     },     buildboat : function() {         console.log("this works too");         (boatlen = 1; boatlen < 4; boatlen++) {             xpos = xpos++;             boatpos = "cell_" + xpos + "_" + ypos;         }     },     addnumber : function() {         document.getelementbyid("test2").innerhtml = "hello"; //debug line     } }

the addnum() function there debug.

you there.

in case boatgrid object , addnumber 1 of it's method. use this.addnumber()

var xpos; var ypos; var boatgrid = {      selectpos : function() {         console.log("it works"); //want try calling function addnumber() here      this.addnumber();   // changed here      (boatnum = 1; boatnum < 4; boatnum++) {             xpos = math.floor(math.random() * 8);             ypos = math.floor(math.random() * 10 + 1);         }     },     buildboat : function() {         console.log("this works too");         (boatlen = 1; boatlen < 4; boatlen++) {             xpos = xpos++;             boatpos = "cell_" + xpos + "_" + ypos;         }     },     addnumber : function() {         //document.getelementbyid("test2").innerhtml = "hello"; //debug line    document.write('<pre>add number called</pre>')      } } boatgrid.selectpos();
