本文介绍了AngularJS行的总和NG-重复的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我动态添加行我表NG-重复,从一个数组的到来。
现在我想获得每行的所有款项(group.sum * group.perc / 100.0)的总和。我需要在一个变量,因为我需要进一步计算该值。谢谢
HTML
< TR NG重复=组中groupsArr>
< TD类=总-行NG模型=税> {{group.sum * group.perc / 100.0 |货币:}}< / TD>
< / TR>
SCRIPT
VAR taxTotals = 0;
VAR taxTotals =
对于(i = 0; I< group.length;我++){
将TaxTotal =将TaxTotal +组[I] .taxes;
};
的console.log(taxTotals);
};
解决方案
创建过滤器:
app.filter('sumFilter',函数(){
返回功能(组){
变种taxTotals = 0;
对于(i = 0; I< groups.length;我++){
将TaxTotal =将TaxTotal +组[I] .taxes;
};
返回taxTotals;
};
});
使用的过滤器$服务:
app.controller('myController的',函数($范围,$过滤器){
$ scope.groups = []; 变种taxTotals = $滤波器('sumFilter')($ scope.groups);
的console.log(taxTotals);
});
使用它在你的HTML:
< TR NG重复=组中groupsArr>
< TD类=总-行NG模型=税> {{group.sum * group.perc / 100.0 |货币:}}< / TD>
< / TR>
&所述; TR>
< B>税收总计:< / B> {{groupsArr | sumFilter |货币}}
< / TR>
I add dynamically rows in my table with ng-repeat, coming from an array.
Now I want to get the sum of all sums per row (group.sum * group.perc / 100.0). I need it in a variable because I need this value for further calculations. Thank you
HTML
<tr ng-repeat="group in groupsArr">
<td class="total-rows" ng-model="taxes">{{group.sum * group.perc / 100.0 | currency :""}}</td>
</tr>
SCRIPT
var taxTotals = 0;
var taxTotals =
for (i=0; i<group.length; i++) {
taxTotal = taxTotal + group[i].taxes;
};
console.log(taxTotals);
};
解决方案
Create a Filter:
app.filter('sumFilter', function() {
return function(groups) {
var taxTotals = 0;
for (i=0; i<groups.length; i++) {
taxTotal = taxTotal + groups[i].taxes;
};
return taxTotals;
};
});
Use the $filter service:
app.controller('myController', function($scope, $filter) {
$scope.groups = [...];
var taxTotals = $filter('sumFilter')($scope.groups);
console.log(taxTotals);
});
Use it in your HTML:
<tr ng-repeat="group in groupsArr">
<td class="total-rows" ng-model="taxes">{{group.sum * group.perc / 100.0 | currency :""}} </td>
</tr>
<tr>
<b> Tax Totals: </b> {{ groupsArr | sumFilter | currency }}
</tr>
