with the same primary key hash value share the same partition in DynamoDB, the local level two index contains only items that are stored in the same location (the same partition). Therefore, LSI can be used to query items that have the same primary key hash value, but with different range keys.It is important to note that all the GSI related to the table must be specified when the table is created. A GSI index does not require that indexed properties be unique. The GSI supports eventual consist
Double-click (Multi-click) event in Android and double-click in androidFirst, easy to think. To achieve double-click, you need to save the time when you click for the first time. You need to use the variable, and then compare it with the time when you
In principle, do not bind a click or double-click event to the same Dom element, which may inevitably affect each other.
I encountered the following problem: a click and dblclick (jquery used) are bound to the same Dom element. In Firefox, double-click events are triggered sometimes, but sometimes they do not, conject
In one case, two aspects are simulated: click a super connection event.Firefox compatible FunctionsAdd an onclick event to htmlanchorelement
CopyCode The Code is as follows: Try {
// Create a element so that htmlanchorelement is accessible
Document. createelement ('A ');
Htmlelement. Prototype. Click = function (){
If (typeof this. onclick = 'function '){
If (this. onclick ({type: '
The difference between jQuery: $ (). click () and $ (document ). on ('click', 'element to be selected ', function () {}), jquery. click
The emergence of jQuery greatly simplifies dom operations. However, if you do not carefully read the api and perform operations, you do not know the biggest advantages and usage methods. Take $ ().
After a button click event is bound with jquery, everything works after the first click. The second click actually runs twice, and more will be performed in the future.
Later, I checked the document and found thatJquery click is not to replace the original function, but to add, So the number of executions increases.
