Introduction to implementing front-end Paging for table and ul li in js This article mainly introduces js to implement front-end Paging for table and ul li. If you need it, refer The Code is as follows: (Function ($ ){ $. Fn. tablepage = function (oObj, dCountOfPage, fresh_id ){ Var dPageIndex = 1; Var dNowIndex = 1; Var sPageStr = ""; Var dCount = 0; Var oSource = $ (this ); Var sNoSelColor = "# CCCCCC ";

. The role of Array.prototype.slice.call (NodeList) is to convert an element with the length property into an array, which takes advantage of the IndexOf method to get the index value of Li.Scenario 4-----The use of virtual properties;Script> varnodeList=document.getElementsByTagName ('Li'); for(varI=0; Inodelist.length; I++) {Nodelist[i].index=i; Nodelist[i].addeventlistener ("Click",function(e) {Console.log ( This. Index)},false) }Script>Scenario 5----The use of custom attributes;Adding

A few days in the three columns with CSS layout of the sudden thought of such a method, the idea of their own feel a little crazy, if there is anything wrong in the place please you feel free.

An obvious problem with Li's Float:left method is that it cannot be centered (horizontally) and can only be centered by using Padding-left or Margin-right methods. Always thought to the UL Li Center alignment already mastered. But the recent project to discover the previous Float:left method of Li is obviously a problem, that is, can not be centered (horizontal), can only use the Padding-left or Margin-right method to fix its center. However, this may

symbol table is a data structure for storing key-value pairs, which supports two kinds of operation insertion and lookup, which is to put a new set of key-value pairs into the table and then get corresponding values according to the given key, which is similar in common dictionary principle in programming language. Symbol table is a typical abstract data structure, in the life of the application of a lot of scenes, can be opened according to the key,

In the Execution Plan, we often see keylookup and ridlookup operations, and the cost is very large. What are key lookup and rid lookup: Ridlookup is a bookmarked query on the stack using the provided row identifier (RID ). KeylookupThe operator is used to search for bookmarks on tables with clustered indexes. The difference is thatKey LookupYou can use the clustered index key value for search. The RID

Half-lookup of IOS algorithm (5) and half-lookup of ios Algorithm Binary Search, also known as semi-query, has the advantage of a small number of times, fast query speed, and good average performance. Its disadvantage is that the table to be queried is an ordered table and it is difficult to insert or delete data. Therefore, the half-fold lookup method is suitabl
