picture, or a request is sent to the server when SRC is empty. You can point to the address of loading. Note: The picture should specify the width height When the page is loaded, the DATA-SRC attribute value of the IMG tag in the viewable area is first negative to SRC, and then the scrolling event is monitored to load the picture that the user is about to see. This will enable lazy loading. Code Before you write code, you need to know the various heights. Read this article firs

:44Testing Strategies for MonkeyI. ClassificationThe monkey test uses different test scenarios for different objects and for different purposes, first of all, the object, purpose, and type of the test are as follows:The types of tests are divided into: application stability testing and stress testingTest objects are divided into: single apk and APK collectionThe objectives of the test are: problem-solving tests (ignoring exception tests) and acceptance tests (tests that do not ignore exceptions)

We know that JS some events such as Resize,mousemove will be triggered continuously, such as our simple one Scroll event:function SCROLLFN () { console.log (1)}window.onscroll=SCROLLFNWe need to do something at the time of scrolling, as we can see, we are simply the console, and the function executes nearly 20 times during a rolling process, and if the function has more complex methods, such as manipulating the DOM or other interactions, it will seriously affect performance. To avoid this pro

"Sohu Driving School" manual more safe How to change the most reasonableHttp://auto.sohu.com/20131009/n387698496.shtmlAlthough most of the driving schools use manual models, but most of the novice and hand-foot coordination of the women are not compatible with the manual model of the Resistance, but also to see the road to change gears, traffic jams frequently, uphill start to find oil from the timing is very difficult ... There are so many reasons not to open the manual model. But recently open

a loop, performance is affected. When you get a multiple-attribute lookup for a single value, such as: var query = window.location.href.substring (Window.location.href.indexOf ("?")); You should reduce unnecessary property lookups and cache window.location.href as variables. var url = window.location.href;var query = url.substring (Url.indexof ("?")); function throttling Suppose you have a search box that binds the onkeyup event to the search box so that every time the mouse lifts, it sends a r

a site to configure IIS at any time and use only 90% of the CPU processor X (or all processors. The CPU throttling feature of IIS 7 is desperate: you either stop the process or do not take any action Second, IIS 7's CPU Throttling is bound to a given application pool. If each website has a separate pool, This is not bad. If you place the CPU core in this way, you can. Even for Single-core websites with low CPU usage .) However, if you have multiple websites that share the same application pool

1, first of all, said the start of automatic gear: A lot of friends start to give too little oil, this is not necessary, in fact, is not good. Automatic gear shift design in 2500 turn (when the hot car at about 2200 shift gear), too little oil, up to less than 2500 rpm, shift is very slow, not only the engine sound, and easy to make the engine to produce carbon, but also affect the life of the engine, so give a little more oil, so that the speed of 2500 turn quickly. The aim is not only to start

, S1 and S is only two references, they are only the joystick, they point to the same object, manipulating the same object, through which they get the same object content. This is like the car brakes and throttle, they manipulate the speed, if the car starts at 80, then you step on the accelerator, the car accelerated, if the speed rose to 120, then you step on the brakes, at this time the speed is starting from 120, if the drop to 60, and then step o

This high frequency response, if the method is more complex, will consume more pe
