Question

我想创建一个canvas元素并将图像放入其中。在此之前，我想在画布中绘制任何东西，然后取回图像并放入我的div

像这样

  var randomArr = ['1','4','3'];

  function check(arrA,arrB){
    for(i=0;i<arrA.length;i++){
      if(arrB.indexOf(arrA[i])==-1){return false;}
    }
    return true;
  }

  function superCheck(){
    var arr1 = ['1','2','3']
    ,  arr2 = ['4','5','6']
    ,  arr3 = ['7','8','9']
    ,  arr4 = ['1','4','7']
    ,  arr5 = ['2','5','8']
    ,  arr6 = ['3','6','9']
    ,  arr7 = ['1','5','9']
    ,  arr8 = ['3','5','7'];
    var arrs = [arr1, arr2, arr3, arr4, arr5, arr6, arr7, arr8];

    for(i=0;i<arrs.length;i++){
      if(check(arrs[i],randomArr)){return true;}
    }
    return false;
  }

  console.log(superCheck());

我该怎么办“????????????”

谢谢你们

Answer 1

我明白了

   var dataURL = canvas.toDataURL();
        $("#palco").html("<image width='"+largura+"'  height='"+altura+"' id='zoom'  src='"+dataURL+"'   >");
