在这个上绞尽脑汁.我有以下代码：JavaScript游戏的第一阶段.所有对象都是明确定义的,我正在使用jQuery进行DOM交互.该谜题是使用以下JS代码创建的：

var mypuzzle = new puzzle("{solution:'5+6+89',equations:[['5+3=8',23,23],['5+1=6',150,['5+3=6',230,23]]}");

但是,代码底部的循环不会比第一次迭代更进一步.知道为什么吗？根本没有错误.

function equationBox(equation,top,left) {//draggable equation Box
    this.reposition = function() {
        this.top = 0;
        this.left = 0;
    }
    this.top = 0;//make random
    this.left = 0;//make random
    this.equation = equation;
    if(top && left) {
        this.top = top; 
        this.left = left;
    }
    this.content = this.equation.LHS.string + 'Box = function(equationBox) {
        $('#puzzle #equations').append(equationBox.DOM);
    }
    this.init = function() {
        //this.drawPuzzleBox();
        this.json = JSON.parse(json);
        this.solution = new expression(this.json.solution || '');
        this.equations = this.json.equations || [];
        var iterations = this.equations.length;
        for(i=0;iBox(new equationBox(stringToEquation(this.equations[i][0]),this.equations[i][1],this.equations[i][2])); 
        }
    }
    this.init();
}
