javascript - block consecutive $http request -


i working in angular project there have grid data , actions.

on clicking 1 of action in onclick function ajax request going server side once in life time process.

but when user consecutively click action button before first request's response came same call going server more once ends in error.

i have tried disable action button before ajax request though cant prevent multiple request. there method block second request?

my code is

$http({   method: 'post',   url: urls.api_url_serv + 'notification/read?token=' + token,   transformrequest: transformrequestasformpost,   withcredentials: false,   headers: {     'content-type': 'application/x-www-form-urlencoded'   },   data: {     notification_id: notification_id   } }).then(function(response) {   var data = response.data;   //some actions   }).catch(function(response) {   var status = response.status;    // actions  }); 


<span ng-class="{'disabled': read_disable}"> <i class="fa fa-envelope" ng-click="markasreadnotification(row.id)"></i> </span>

you can idiomatic way example (using es6 syntax use this in simple way)

this.makerequest = () => {   if (!this.request) {     this.request = $http({       method: 'post',       url: urls.api_url_serv + 'notification/read?token=' + token,       transformrequest: transformrequestasformpost,       withcredentials: false,       headers: {         'content-type': 'application/x-www-form-urlencoded'       },       data: { notification_id }     });      this.request.success((data) => {       // if want let user request, after 1 finished       this.request = undefined     })   } }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
