AlipayJSBridgeReady

H5 Container is initialised after window.onload and AlipayJSBridgeReady event is emitted when the global variable AlipayJSBridge is created.

AlipayJSBridge injection is an asynchronous process, please listen to AlipayJSBridgeReady event before invoking any JSAPI. We strongly recommend to use [alipayjsapi](alipayjsapi/) to simplify the process of initialising JSAPI.

Usage

function ready(callback) {
  // Invoke directly if JSBridge is already injected
  if (window.AlipayJSBridge) {
    callback && callback();
  } else {
    // Otherwise listen to AlipayJSBridgeReady event
    document.addEventListener('AlipayJSBridgeReady', callback, false);
  }
}
