输入字段(type=“number”)一旦内容更改,就会失去angularjs的双向“BIND”属性
Input fields (type="number") loose their two-way 'BIND' property of angularjs once their content is changed.
我的问题很简单,但本质上是难以捉摸的。当您加载索引.php时(作为使用 xampp 的本地主机),您将看到一个简单的表单。现在这个表单上有多个元素,它仍在进行中,因此多个错误的可能性是合理的。但是,有一个错误真的很烦人。
问题:
更改截止日期元素时,以下输入的内容 盒子会因为与它绑定而发生变化。现在它不会 不管你更改截止日期多少次,因为每次 字段中的值将相应更改,这要归功于 angularjs。
当您更改输入字段的值时,BUG 会悄悄潜入。说 最初是 27,然后你把它改成 ,idk 说 10。*现在 如果更改截止日期,则更改的输入字段保持不变 * 即值为 10,而我希望它仍然改变。
此外,如果你们中的一个是angularjs编码员的神化, 他为我提供了一些提示,我只想说....."我很感激 那"。

Ctrl-add-service.js (controller)
// ctrl-add-service.js Controller for the add service option in the nav bar of the home screen.
var mainApp = angular.module("mainApp",[]);
mainApp.controller('ctrl-add-service',function($scope, DueDateService){
$scope.value ='1';

};
});
服务.js(应用程序的服务)
// services.js services.js of the account direcotry of the project. It is used by the mainApp.
//DueDateService
mainApp.service('DueDateService', function(){
this.month = function(date) {
var temp = new Date(date);
month = temp.getMonth();
console.log(month+1+" is the month");
return (month+1);
};

console.log(date+" is the date");
return (date);
};
this.fields = function(month,period) {
var lap = parseInt(period); // possible values of lap can be [12,6,4,1]
var iteration = 12/lap; // possible values of iteration can be [1,2,3,12]
var selectedFields = [true,true,true,true,true,true,true,true,true,true,true,true];
for (var i=1; i<=iteration; i++) {
if(month>12) {
month = month - 12;
}
selectedFields[month-1]= false;
month = month + lap;
}
return selectedFields;
};
});
我认为您需要将ng-value
更改为ng-model
并创建日期Array
,如下所示:
ng-model='dates[0]'
ng-model='dates[1]'
ng-model='dates[2]'
...
您的控制器将是这样的:
var date = DueDateService.date($scope.dueDate);
$scope.dates = Array(12).fill(date);
请看这个 plunker:https://plnkr.co/edit/p8O14Y80hCWyNmxnYxbF
在以下几行中,你为什么要采用ng值,据我所知,你将不得不采用ng-model="date",这将正常工作。
查看 ng 值用法https://docs.angularjs.org/api/ng/directive/ngValue
<div style="display:inline-block;"><label>Jan</label><input type="number" class="form-control" ng-value='date' ng-model="date" ng-disabled='fields[0]' ng-required='!fields[0]'></div>
