Implement Windows8Metro style with pure Javascript _ javascript tips-js tutorial

The style of Windows8Metro is designed to implement navigation of website or system functions. This article will introduce how to use pure Javascript to implement the style of Windows8Metro. If you are interested, refer Main features of Metro Style Design

1. The Windows 8 Metro style design enables navigation of website or system functions

2. Pure Javascript implementation

3. Support all common browsers such as IE, 360, and Chrome

4. Supports special effects such as rounded corners, shadows, and Card Switching

5. Support card zoom-in, zoom-out, add, and delete Functions

6. You can customize the background color, background image, card image, and card text of a card.

7. Any switch between cards

Metro Style

Metro Algorithm

Code for card display:

The Code is as follows:

Str ='

';
Str + ='

';
Str + ='

';
Str + ='

';

Mobile cell JS script:

The Code is as follows:

Function moveItem (objid, indexList ){
// Determine whether to move effectively.
Var curItem = getCurItem (objid );
Var curIndex = curItem. index;
For (var I = 0; I Var miIndex = parseInt (indexList [I]);

AlertInfo ("the last column cannot be increased! ");
Return false;
}
If (miIndex> = (rowSize * colSize )){
AlertInfo ("cannot exceed three lines! ");
Return false;
}
Var cellnum = getItemCellNum (miIndex );
If (cellnum! = 1 ){
AlertInfo ("Currently, only one cell can be moved! ");
Return false;
}
}

}
}

}
}

Return false;
}

// Del (moveItem. id );
}

}

// Check the vacant cells. If yes, the null object is filled.
For (var I = itemArray. length-1; I >=( rowSize * colSize); I --){
