const { XCall } = require('js-xcall');
import { XCall } from 'js-xcall';
import XCall from 'js-xcall';
<script src="xcall.min.js"></script>
const { XCall } = $call;
XCall.addCallBack('test', function () {
console.log('test-browser', arguments);
});
使用
console.log(XCall);
XCall.addCallBack('test', function () {
console.log('test1', arguments);
});
var test = function (data1, data2) {
console.log('test2', data1, data2);
};
XCall.addCallBack('test', test);
XCall.dispatch('test', 123, 456);
// test1 [Arguments] { '0': 123, '1': 456 }
// test2 123 456
console.log(
'hasCallBack-test',
XCall.hasCallBack('test', test),
XCall.hasCallBack('test', () => {}),
XCall.existEvent('test')
); // hasCallBack-test true false true
XCall.getCount(); // 1 (event count)
XCall.removeCallBack('test', test);
XCall.existEvent('test'); // true
XCall.getCount('test'); // 1 (callback count)
XCall.dispatch('test'); // test1 [Arguments] {}
XCall.deleteEvent('test');
XCall.getCount('test'); // 0 (callback count)
XCall.existEvent('test'); // false
XCall.setOnceEvent('test-once', test);
XCall.existEvent('test-once'); // true
XCall.getCount('test-once'); // 1 (callback count)
XCall.getCount(); // 1 (event count)
XCall.dispatch('test-once');
XCall.existEvent('test-once'); // false
XCall.getCount(); // 0 (event count)
XCall.dispatch('test-not'); // Error: 未找到回调事件 test-not 的监听
XCall.addCallBack('hello', test); // 只有一个事件
XCall.existEvent('hello'); // true
XCall.dispatch('hello', 0, 1); // test2 0 1
XCall.removeCallBack('hello', test); // remove 时直接会删除监听,释放内存。
XCall.existEvent('hello'); // false
