Wrote half a genius to write well, exhausted.The function of the method is to automatically match the data in the HTTP request corresponding to the entity parameter name, so that the other methods can be used alone, but it is best to write the extension method alone, directly point out.Automatically matches the data in the HTTP request corresponding to the entity parameter name (performance is not optimal)

This method is used to precisely filter out a matching subset on top of the selector (you can use a leading limit range):1.start: the position at which to start selecting a subset. The first element is 0. If it is a negative number, you can select it from the tail of the collection2.end: end Pick Your own position, if not specified, it is the end of itself3. The parameter contains the start, does not contain the end [start, end]Instance:[jquery filter Slice (start, [end])] This method is used to

the index locations that have a value of 3, such as: You can see that the value of the element corresponding to the index 5, 9, 14 is 3. This way you can easily achieve your goals. But for indexes within a certain range of changes this is not going to happen. The following method is to think out of the compromise approach, relatively stupid, Master Qing spray. (2) To resolve a range of value index lookups by an auxiliary array We build an array that identifies the index of the element, and the

]); print_r ($ img_array ); The above will match the remote image, and we need to keep it locally. Note the following two points: 1. image storage path (image storage directory) 2. actually accessing the image address The following is a complete example: (you can save it to the local server and modify the corresponding places for testing) Php saves the remote image to the local device. The php regular expression matches the image address in the ar
