Combat data binding: pagination navigation based on the client

Pagination | client | Data thinking: With pure JS method, only by judging the current page of the file name, and then calculate the upper and lower page address, home and last need to configure in the script, and finally generate navigation code. Data-bound methods are much simpler, set datapagesize, and then page by FirstPage (), PreviousPage (), NextPage (), and LastPage () methods.

code example:

1. Pure JS, page navigation based on the filename page.js script file code

Number.prototype.add0 = function () {//extension of numeric type, mainly used to make up 0 before a number is smaller than a certain number of digits until the multiple is reached
Return (new Array (len). Join ("0") +this). Slice (-len)//back string, new Array (len). Join ("0") gets len a connected "0" and then adds to the number, And intercept the Len bit from the right of the resulting string.
}
String.prototype.mlink = function (n) {//extension of character type, primarily used to generate links based on numbers in file names
Return This.link (prefix+n.add0 () +suffix)//returns HTML code with a string of linked text, prefix+n.add0 () +subffix as the link address
}
var prefix = "page"//filename Prefix
var suffix = ". htm"//filename suffix
var first = 1//number in File name of page one
var last = 23//The number in the filename of the final page
var len = 2//The number of digits in the file name, from the above four variables known as "page01.htm" and "page23.htm" this form
var cur_page = Location.href.match (new RegExp (prefix+) (\\d+) "+suffix," I ")" [1]|0Find a matching number from the current page address
var previous = cur_page-1//The number in the filename of the previous page is minus 1 for the current page
var next = the number in the filename of the next page is plus 1 for the current page cur_page+1
if (cur_page = i) previous = first//If the current page is the home page, then the link on the previous page is the home page
if (Cur_page =) Next = last///if the current page is last, the link to the next page is the end
navbar.innerhtml = ["Home". Mlink (first), "Prev". Mlink (previous), "next page". Mlink (Next), "End". Mlink (last)].join ("")///in ID Generate navigation links in NavBar objects

Then use the <div id= "NavBar" ></div><script src= "Page.js" ></script> calls on each page

2. Data binding to the table, and then using the object's page-flipping method to achieve

Click to view the effect of the operation

Note: You must set the DataPageSize property of the table, and the data source corresponds to the ID of the XML object, and the object on the page must correspond to the table object that binds the data

Tips:

DataPageSize Sets or gets the number of records displayed in a table bound to a data source
DATASRC Sets or gets the data source used for data binding
DATAFLD Sets or gets the field specified by the Datasrc property that binds to the given data source of the specified object
FirstPage The first page record of the dataset that binds the table
PreviousPage the previous page record of the dataset that binds the table
NextPage the next page record of the dataset that binds the table
LastPage displays the last page record of the dataset that binds the table

Tip: If you are displaying only one record at a time, you can also use the recordset to move the method:
