premise of chained programming: The return value of the object after it invokes the method or the current object, you can continue to invoke the method, otherwise you cannot continue to invoke the method.4. ExperienceIn JQuery, in general, the object calls the method, and if the method is to set a property (the method has parameters that set the value of the property), then the return value is almost the current object, you can continue to chain programming.Example:$("#dv").css("width","10px").

[20141030] 68 effective ways to write high-quality JS code (III)No.11, Master closureTips: A function can reference a scope variable that is defined outside it. Closures have a longer life cycle than the functions that create them. Closures internally store references to their external variables and can read and write these variables. //第一个事实：JavaScript允许你引用在当前函数以外定义的变量。function testClosures(){ var all = ‘Test‘; func

Search Engine Algorithm Research Topic III: Introduction to Clustered and nonclustered indexesIntroduction to Clustered IndexesIn a clustered index, the physical order of the rows in the table is the same as the logical (indexed) Order of the key values. A table can contain only one clustered index.If it is not a clustered index, the physical order of the rows in the table does not match the logical order of the key values. Clustered indexes have fast

(i) preparatory work 1. Create a new module (name customization) that holds the module code to be published. 2. Create a new setup.py module (storing the metadata of the module, describing the relevant information). 3. Create a new folder (the name matches the name of the module you want to publish), and then put the above 2 modules in a folder. For example, I create a module disposelist.py that processes list data, and the code is as follows:# Create a function to proce
