javascript - Saving images from URL using JSzip -

-

I am using JSzip to download HTML of a div. Div has images inside it (they are not base 64 encoded) Is there a way that I can use JSZ to download files from my Image Path URL? Or should they be 64 encoded?

My current code is just the original demo code from JSzip site () 

  var zip = new JSZip (); Var email = $ ('results'). Html (); Zip.file ("test.html", email); Var content = zip.generate ({type: "blob"}); // View FileSaver.js saveAs (content, "example.zip");

First you need to download all the images with Ajax. If they are on the same domain you are in luck, otherwise you need a corse or proxy. 

  var xhr = new XMLHttpRequest (); Xhr.addEventListener ('Load', function () (if (xhr.status == 200) {// something with xhr.response (not response text), which should be a blob}}); Xhr.open ( 'GET', 'http: //target.url'); Xhr.responseType = 'blob'; xhr.send (zero);

When you get the image, Src > all must be manipulated in and lt; img & gt; , or you replace them with base64 or they were referenced in a folder, you can use them with JSZip Folder is entered 

  var reader = new FileReader (); Reid Kolod = function () {showout.value = this.result;}; reader.readAsDataURL (xhr.response);

The UITapGestureRecognizer crashes because the application crashes Swipe is not the cause of any problems made at very short distances, but You can show those errors made at a long stretch: - [UITapRecognizer name]: Non-accredited selector example sent for example 0x17ee27c0 Where 0x17ee27c0 is a random value *** Expected exception 'NSInvalidArgumentException', due to reason the application ends: '- [UITapRe Cognizer name]:.

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
