js jquery 权限单选 bug修改以及正确代码 购物车数量加减
效果图废话不多直接上代码
用的avalon渲染，其实都是一样的
<div class="shop-arithmetic"> <a href="javascript:;" class="minus" onclick="delpubls(this)">-</a> <input type="number" style="min-height: 20px;font-size: -2.2rem" ms-attr-carid="el.cart_id" ms-attr-price="el.min_price" class="num" ms-attr-value="{{el.buy_num}}"/> <a href="javascript:;" class="plus" onclick="addpubls(this)">+</a> </div>
function addpubls(now){ var previousnode = now.previousElementSibling; var a = parseInt(previousnode.value) a += 1; previousnode.value = a; setcheckallprice() } function delpubls(now){ var nextnode = now.nextElementSibling;//获取下一个节点 var a = parseInt(nextnode.value); a -= 1; a = a > 0 ? a : 0; nextnode.value = a; setcheckallprice() }
上面是购物车加减，
这是效果图，要做到点击下方全选都选中取消，
点击商品，相应的选中取消，
点击单个，选中取消
//某一种商品全部选中 function onegoodsallcheck(now){ var aaa = now.parentNode.parentNode.getElementsByClassName('goodsCheck'); if(now.checked){ for(i=0;i<aaa.length;i++){ // aaa[i].checked = 'checked'; aaa[i].setAttribute('checked','checked'); aaa[i].checked = true; if (i!=0) { var bbb = aaa[i].parentNode.getElementsByClassName('num'); // alert('') bbb[0].className = "num mychecknum"; }; } // $('.checkallnum').text($('.num').length); }else{ for(i=0;i<aaa.length;i++){ // aaa[i].checked = false; aaa[i].removeAttribute('checked'); aaa[i].checked = false; if (i!=0) { var bbb = aaa[i].parentNode.getElementsByClassName('num'); bbb[0].className = "num"; }; } } setcheckallnum(); } //获取当前被选中的数量 给下方赋值 function setcheckallnum(){ var aaa = document.getElementsByClassName('num mychecknum'); var checkallnum = document.getElementsByClassName('checkallnum'); for (var i = checkallnum.length - 1; i >= 0; i--) { checkallnum[i].innerText = aaa.length; }; setcheckallprice(); } //获取当前所有价格，给下方赋值 function setcheckallprice(){ // checkallprice var aaa = document.getElementsByClassName('num mychecknum'); if (aaa.length==0) { var ccc = document.getElementsByClassName('checkallprice'); ccc[0].innerText = '0.00'; return false; }; //算出选择的总价 var allprice = 0; for (var i = aaa.length - 1; i >= 0; i--) { var nowprice = aaa[i].getAttribute('price'); var nownum = aaa[i].value; allprice = allprice+(nowprice*nownum); }; var ccc = document.getElementsByClassName('checkallprice'); ccc[0].innerText = allprice; } //单选的按钮 function xuanonecheck(now){ var aaa = now.parentNode.getElementsByClassName('num'); // alert(aaa.length); // return false; if(now.checked){ //取消 now.setAttribute('checked','checked'); //设置后面input为选中、 aaa[0].className = "num mychecknum"; }else{ // 默认 now.removeAttribute('checked'); aaa[0].className = "num"; } setcheckallnum(); }
因为很多地方不能用jquery，所以这里用了jquery和原生js
他们和html的checked交互不同，需要看一下，不然会出现bug，解决办法上面已经有了
贴一下全部代码，是微信端采用avalon，public.js，common.css，apicloud.等等
