如何在 javascript 的任何地方全局访问 jquery function 中的变量？

Question

const levelButtons = document.querySelectorAll('input[name="level"]');
Array.prototype.forEach.call(levelButtons, function(btn) {
  btn.addEventListener('change', function(){
   var selectedLevel = this.value;
  });
});
console.log(selectedLevel);

I want to use selectedLevel variable as a parameter (in place of 5000) in angularjs.

<tr ng-repeat="user in users | filter : searchtxt | filter: greaterThan('Fees', 5000)">
<td class="Program_Name">{{user.Program_Name}}</td>
<td class="Institute">{{user.Institute}}</td>
<td class="Fees">{{user.Fees}}</td>

Answer 1

You should define a global variable or instead you can create a function that return selectedLevel and use this return in your ng-repeat
