I have such type of program.
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.records = [
{
"Amt" : "500",
},
{
"Amt" : "800",
},
{
"Amt" : "1580",
},
{
"Amt" : "1122",
}
]
$scope.value=function(d, x)
{
x.balance = x.Amt - d;
if(d > x.Amt){
$scope.isExceeded = true;
} else {
$scope.isExceeded = false;
}
}
});<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body ng-app="myApp">
<table ng-controller="myCtrl" border="1">
<tr>
<td>Amt</td>
<td>Balance</td>
<td>Entered Amt</td>
<td ng-if="error"> Error</td>
</tr>
<tr ng-repeat="x in records">
<td>{{x.Amt}}</td>
<td>{{x.balance}}</td>
<td><input type="text" ng-model="d" ng-change="value(d, x)"></td>
<td ng-if="d > x.Amt" ng-model="error">Please enter less than {{x.Amt}}</td>
</tr>
<tr>
<td colspan="4"><input type="button" value="Submit" ng-disabled="isExceeded"></td>
</tr>
</table>
</body>
</html>What I want is submit button should become disable if any Entered Amt value exceeds the Amt value.
I m not getting an idea of how can I achieve this type of condition.I an new to angularjs.
You can have an variable isExceeded and use it in the angular markup with ng-disable directive to disable the button.
<body ng-app="myApp">
<table ng-controller="myCtrl" border="1">
<tr>
<td>Amt</td>
<td>Balance</td>
<td>Entered Amt</td>
<td ng-if="error"> Error</td>
</tr>
<tr ng-repeat="x in records">
<td>{{x.Amt}}</td>
<td>{{x.balance}}</td>
<td><input type="text" ng-model="d" ng-change="value(d, x)"></td>
<td ng-if="d > x.Amt" ng-model="error">Please enter less than {{x.Amt}}</td>
</tr>
<tr>
<td colspan="4" ng-disable="isExceeded"><input type="button" value="Submit"></td>
</tr>
</table>
</body>
and check it in the angular controller like
$scope.value=function(d, x)
{
if(d > x.Amt){
$scope.isExceeded = true;
} else {
x.balance = x.Amt - d;
$scope.isExceeded = false;
}
}
