Window. js mainly contains some page operations _ javascript skills

It mainly gets some information about page elements, so it is named window. js. If you want to learn it, refer to it. The Code is as follows:

// Handle page exceptions
Function Exception (){
}

// Common interface of page elements
Function View (){
// Page Element
This. element = null;
// Text color
This. color = null;

// Set the style
This. setStyle = function (name, value ){
Eval ("this. element. style." + name + "= '" + value + "'");
}
// Obtain the style
This. getStyle = function (name ){
Return eval ("this. element. style." + name );
}

// Set floating Style
This. setFloat = function (styleFloat ){
This. setStyle ("styleFloat", styleFloat );
}
// Set the background color
This. setBackgroundColor = function (backgroundColor ){
This. setStyle ("backgroundColor", backgroundColor );
}
// Obtain the background color
This. getBackgroundColor = function (){
Return this. getStyle ("backgroundColor ");
}
// Set the object width
This. setWidth = function (width ){
// Alert (width );
This. setStyle ("width", width );
}
// Set the object width
This. setHeight = function (height ){
This. setStyle ("height", height );
}
// Set page Positioning
This. setPosition = function (position ){
This. setStyle ("position", position );
}
// Set the Layer
This. setZIndex = function (zIndex ){
This. setStyle ("zIndex", zIndex );
}
// Left distance
This. setLeft = function (left ){
This. setStyle ("left", left );
}
// Distance above
This. setTop = function (top ){
This. setStyle ("top", top );
}
// Whether to wrap the line
This. setWhiteSpace = function (whiteSpace ){

}

// Set attributes
