1.angularjs directive defines a comparison function that gets the incoming value dynamically and calls this method as soon as the input box changes. The
code is as follows:
.directive("lessThan",[function () {
return {
require: "ngModel",
restrict: "A",
priority:"9",
link: function ($scope, element, attrs, ctrl) {
var lessThan = function (inputValue) {
inputValue = inputValue || "";
console.log($scope[attrs.lessThan]);
if(attrs.lessThan){
if(inputValue>attrs.lessThan){
inputValue = ""
}
}
return Number(inputValue);
};
ctrl.$parsers.unshift(lessThan);
lessThan($scope[attrs.ngModel]);
}
};
}])in html:
<input
type="text"
ng-model="hopeCostRate"
less-than = "{{proposal.hopeRate}}"
>problem encountered: proposal.hopeRate is another model, but each change can not get this value, always "", do not know how to solve. Call for help ~
