禁用Spreader单击

Question

我试图禁用点击'Spreader'按钮。似乎无法阻止它关闭。我有一个想要保留的onmousedown事件，但我不想关闭吊具。有人知道禁用点击吊具的最佳方法吗？

Answer 1

您可以设置minPercent属性以满足您的需求。

var wheel;

window.onload = function () {
  wheel = new wheelnav("wheelDiv");
  wheel.spreaderEnable = true;
  wheel.createWheel(["This", "is", "custom", "spreader"]);
  wheel.spreadWheel();

  var wheelspreader = document.getElementById("wheelnav-wheelDiv-spreader");
  var wheelspreadertitle = document.getElementById("wheelnav-wheelDiv-spreadertitle");
  wheelspreader.onmousedown = function() {openSpreader();}
  wheelspreadertitle.onmousedown = function() {openSpreader();}
};

var openSpreader = function() {
  wheel.minPercent = wheel.maxPercent;
}

这是JS Bin。
