window.js 主要包含了页面的一些操作

复制代码 代码如下:

//处理页面异常
function Exception() {
}

//页面元素共同接口
function View() {
//页面元素
this.element = null;
//文字颜色
this.color = null;

//设置样式
this.setStyle = function(name, value) {
eval("this.element.style." + name + " = '" + value + "'");
}
//获取样式
this.getStyle = function(name) {
return eval("this.element.style." + name);
}

//设置浮动样式
this.setFloat = function(styleFloat) {
this.setStyle("styleFloat", styleFloat);
}
//设置背景色
this.setBackgroundColor = function(backgroundColor) {
this.setStyle("backgroundColor", backgroundColor);
}
//获取背景色
this.getBackgroundColor = function() {
return this.getStyle("backgroundColor");
}
//设置对象宽度
this.setWidth = function(width) {
//alert(width);
this.setStyle("width", width);
}
//设置对象宽度
this.setHeight = function(height) {
this.setStyle("height", height);
}
//设置页面定位
this.setPosition = function(position) {
this.setStyle("position", position);
}
//设置层
this.setZIndex = function(zIndex) {
this.setStyle("zIndex", zIndex);
}
//左边距离
this.setLeft = function(left) {
this.setStyle("left", left);
}
//上边距离
this.setTop = function(top) {
this.setStyle("top", top);
}
//是否换行
this.setWhiteSpace = function(whiteSpace) {
this.setStyle("whiteSpace", whiteSpace);
}

}

//设置属性

}

//加入自定义属性
