I encountered a control problem in the project. I used the panel drag effect written in JQ before. I want to transplant it to angular code but I don’t know how to deal with it. Please let me know.
JQ code
scale = function (btn, bar, title, from, to, initnum) {
//獲取增減溫度的按鈕
this.plus = $('.scale_btn_l a');
this.add = $('.scale_btn_r a');
this.btn = document.getElementById(btn);
this.bar = document.getElementById(bar);
this.title = document.getElementById(title);
this.step = this.bar.getElementsByTagName("p")[0];
this.from = from;
this.to = to;
this.initnum = initnum;
this.init();
};
var length = 0;
scale.prototype = {
init: function () {
var f = this, g = document, b = window, m = Math;
$('.scale_panel .fl').html(f.from + '℃');
$('.scale_panel .fr').html(f.to + '℃');
$('.basemsg span').html(f.initnum + '℃');
if (f.from) {
length = 100 / (f.to - f.from);
var lengthinit = f.to - f.initnum;
var offsetleft = (f.bar.clientWidth / (f.to - f.from)) * (Math.abs(f.to - f.from) - Math.abs(lengthinit)) + length;
this.title.innerHTML = this.initnum;
f.btn.style.left = offsetleft + 'px';
this.step.style.width = offsetleft + 'px';
}
f.btn.addEventListener('touchstart', function(event) {
var x = event.targetTouches[0].pageX;
var l = this.offsetLeft;

You can write jQuery code in the angular instruction. If the jQuery library has been introduced, then the second parameter of the link in the angular instruction is the jQuery object.
angular.directive('foo', function(){
return {
link: function(scope, el){
// TODO 調用你jq的初始化代碼 el.something()...
}
}
})
