How to solve the problem of secondary triggering of angular paging plug-in tm.pagination
This article mainly introduces how to solve the problem of secondary triggering of angular paging plug-in tm.pagination. It has certain reference value. Now I share it with you. Friends in need can refer to it
Today I encountered a front-end problem when learning the paging plug-in of angularjs. When debugging the Google Chrome developer mode, I found that each time I clicked the paging refresh button, two background requests were triggered. Ajax sent two requests to the background. This is For patients with obsessive-compulsive disorder, it is a relatively disgusting and uncomfortable thing.
So I also found a reliable solution on the Internet: http://jqvue.com/tm.pagination/, and this problem was solved in this version of this maintainer. , and pay attention to the use of angularjs versions. But not satisfied with the status quo, I still found my own solution, no injections or medicines, it’s that simple! rough! It's time to show the code!!
var app = angular.module("shopping", [ 'pagination' ]);
app.controller("brandController",
function($scope, $http) {
$scope.reloadList = function() {
//切换页码
$scope.findPage($scope.paginationConf.currentPage,
$scope.paginationConf.itemsPerPage);
}
$scope.reload = true;
//分页控件配置
$scope.paginationConf = {
currentPage : 1,
totalItems : 10,
itemsPerPage : 10,
perPageOptions : [ 10, 20, 30, 40, 50 ],
onChange : function() {
if(!$scope.reload) {
return;
}
$scope.reloadList();//重新加载 这个方法会重复调用两次
$scope.reload = false;
setTimeout(function() {
$scope.reload = true;
}, 200);
}
};
//分页
$scope.findPage = function(page, rows) {
$http.get(
'../goods/findAll?pageNum=' + page + '&pageSize='
+ rows).success(function(response) {
$scope.list = response.rows;
$scope.paginationConf.totalItems = response.total; //更新总记录数
});
}
});I have marked the core code in bold black font, and defined a global variable reload to be stored on $scope , when the reload is triggered for the second time, it is found that this global variable is in the false state, and it is returned directly. Then use the timer setTimeout to reset it after 200 milliseconds. The next refresh will not be affected and only one ajax will be sent per refresh, improving request quality and user experience.
Note: This method is not limited to the problem of repeated sending of ajax requests. For other similar repeated behaviors, you can refer to the implementation ideas of this example. Pay attention to the reasonable use of global variables to reduce memory waste.

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
