moveleft 写出来之后 updata 原来得number-cell 还在。，remove怎么清除不了啊 ！

Question

//update

function updateBoardView(){

$(".number-cell").remove();

for( var i=0 ; i< 4;i++){

for (var j = 0; j <4 ; j++) {

$("#contain").append('<div class="number-cell" id= "number-cell-'+i+'-'+j+'" ></div>');

var numbercell=$("#number-cell-"+i+"-"+j);

if( board[i][j]==0){

numbercell.css({

width:0,

height:0,

top:getTopPos(i,j),

left:getLeftPos(i,j),

backgroundColor:getNumberGroundColor(board[i][j])

});

}

else

{

numbercell.css({

width:100,

height:100,

top:getTopPos(i,j),

left:getLeftPos(i,j),

color:getNumberColor(board[i][j]),

backgroundColor:getNumberGroundColor(board[i][j])

})

}

}

}

}

// 这个是 moveleft 

function moveleft(){

if(!canmoveleft(board))

return false;

//moveleft

for (var i = 0; i < 4; i++) 

for (var j = 1; j < 4; j++) {

if(board[i][j]!=0){

for (var k= 0; k < j; k++) {

if(board[i][k]==0&&noblock(i,k,j,board)){

changeAnamation(i,j,i,k);

board[i][k]=board[i][j];

board[i][j]=0;

continue;

}

else if(board[i][k]==board[i][j]&&noblock(i,k,j,board)){

changeAnamation(i,j,i,k);

board[i][k] += board[i][k];

board[i][j]=0;

continue;

}

}

}

}

updateBoardView();

return true;

}
