单击时获取一行中的值并将其传递给弹出窗口 [英] Get value in a row on click and pass it to popup
问题描述
我需要在单击时获取表格行中的值并将其显示在弹出窗口中
I need to get the value in a row of a table on click and display it in popup
HTML:
<md-data-table-container>
<table md-data-table class="md-primary" md-progress="deferred">
<thead md-order="query.order" md-trigger="onorderchange">
<tr>
<th name="Task To Be Done"></th>
<th name="Office"></th>
<th name="Due Date"></th>
</tr>
</thead>
<tbody ng-click="showAlert($event)">
<tr ng-repeat="dessert in desserts.data" ng-click="showAlert($index)" flex-sm="100" flex-md="100" flex-gt-md="auto">
<td>{{dessert.task}}</td>
<td></td>
<td>{{dessert.due_on}}</td>
</tr>
</tbody>
</table>
</md-data-table-container>
JS:
$scope.desserts = {
"count": 6,
"data": [{
"task": "Frozen yogurt",
"type": "Ice cream"
}, {
"task": "Ice cream sandwich",
"type": "Ice cream"
}, {
"task": "Eclair",
"type": "Pastry"
}, {
"task": "Cupcake",
"type": "Pastry"
}, {
"task": "Jelly bean",
"type": "Candy"
}, {
"task": "Lollipop",
"type": "Candy"
}, {
"task": "Honeycomb",
"type": "Other"
}]
};
$scope.showAlert = function (index) {
$scope.obj = $scope.desserts.data[2];
$scope.task = $scope.obj.task;
alert($scope.task);
console.log($scope.task);
};
我的代码中的问题是我可以获取指定为.data[2]"的数组的值.实际上,当我单击表中的一行时,我需要显示该值以弹出sweetAlert".有什么解决办法
issue in my code is that i could get the value on the array which i have specified ".data[2]". Actually when i click a row in my table i need that value to be displayed to popup "sweetAlert". is there any solution
推荐答案
不要传递 $index
,因为如果底层数据发生变化,这可能有点危险,在这种情况下只是强制您从数组中重新获取该项目.
Don't pass the $index
, as this can be a bit dangerous if the underlying data changes, and in this case it just forces you to re-get the item from the array.
将要显示的实际项目传回警报.
Pass the actual item you want to display back to the alert.
<tr ng-repeat="dessert in desserts.data" ng-click="showAlert(dessert)" flex-sm="100" flex-md="100" flex-gt-md="auto">
<td>{{dessert.task}}</td>
<td></td>
<td>{{dessert.due_on}}</td>
</tr>
除非您在其他地方确实需要,否则不要分配范围.
Don't assign to scope unless you really need it elsewhere.
$scope.showAlert = function (dessert) {
alert('Task:' + dessert.task);
// if you're just using a variable in this function, declare it locally
var dessertType = dessert.type;
console.log(dessertType);
};
