This article will explain in detail how web realizes the check of bulk purchase and displays the total number at the same time. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

When making bulk purchases, we need to click on the goods we need, and then click on bulk purchases.

With each click, the total quantity and amount will be calculated immediately below.

The main code is as follows:

1Jing 2 figure shows the background setting administrative permissions, check the code when. Can be skipped.

{$vc ['classname']} {$vo.title} $(function () {$("# selected") .click (function () {("input [name =' rules []']") .each (function () {$(this) .prop ('checked', true);});}) ("# cancel") .click (function () {$("input [name = 'rules []']") .each (function () {$(this) .prop ('checked', false);});})

This is a bulk purchase.

{$key+1} {$vo.username} {$vo.num} {$vo.addtime | date= "Y-m-d H:i:s", #} {$vo.pricenum} Buy $("# checkall") .click (function () {$("input [name = 'oid []']") .each (function () {this.checked = true;})) Docal ();}); $("# checkallno") .click (function () {$("input [name = 'oid []']") .each (function () {this.checked = false;}); $('# total_pv'). Html ('0'); $('# total_dg'). Html ('0');}) / / calculate function docal () {var formData = $('# ajaxForm') .serialize () / / jQuery.post (url,data,success (data, textStatus, jqXHR), dataType) $.ajax ({type: 'POST', url: "{: U (' Points/docal')}", data: formData, dataType: 'json' Success: function (re) {if (re.code = = 1) {/ / returns the total quantity Total amount / / layer.alert (re.cal.num) $('# total_pv') .html (re.cal.num); $('# total_dg') .html (re.cal.usedgcash);}}, error:function () {layer.alert ('error');}}) Return false;} / / when the selection box is selected by the click. Change (function () {/ * alert ($(this) .attr ("id")); alert ($(this). Val ()); * / docal ();}); $(".action") .click (function () {var buyLink=$ (this) .attr ("link"), $this = $(this) Layer.confirm ('are you sure you want to buy it?' , {title:' operation prompt'}, function (index) {$.post (buyLink,function (data) {if (data.code = 1) {layer.alert (data.message, function () {_ window.location.reload ();});} else {layer.alert (data.message) }}); layer.close (index);});})

Mainly this change has been looking for it for a long time.
