我想通过代码加载一些CSS文件和JS文件。我知道这是异步的，所以我必须使用回调。
我必须支持IE 9。
我的ChromeOptions options = new ChromeOptions()
DesiredCaps = options.ToCapabilities() as DesiredCapabilities;
DesiredCaps.SetCapability("platformName","Android");
DesiredCaps.SetCapability("platformVersion", "8.1");
DesiredCaps.SetCapability("deviceName", "Device 01 Oreo_1440x2560");
DesiredCaps.SetCapability("device", "Android");
AppDriver = new AndroidDriver<AppiumWebElement>(new Uri("http://127.0.0.1:4723/wd/hub"), DesiredCaps, TimeSpan.FromSeconds(300));
执行此代码
initilizer.js在这些回调中，代码由于某些js文件仍未加载而崩溃。他们仍然具有this.importCascadingStyleSheet = function(path, callback){ // load CSS file
var element = document.createElement("link");
element.setAttribute("rel", "stylesheet");
element.setAttribute("type", "text/css");
element.setAttribute("href", path);
this.appendComponent(element, function(){
callback();
});
}
this.importScript = function(path, callback){ // load JS file
var script = document.createElement('script');
script.src = path;
script.type = "text/javascript";
this.appendComponent(script, function(){
callback();
});
}
this.appendComponent = function(cmp, callback){
document.head.appendChild(cmp);
callback();
}
this.getLibPath = function(){
var dir = document.querySelector('script[src$="initilizer.js"]').getAttribute('src');
var fileName = dir.split('/').pop();
var parentDir = dir.replace('/' + fileName, "");
var directoryName = parentDir.split('/').pop();
return parentDir.replace('/' + directoryName, "");
}
this.importStyle = function(fileName, callback){ // import css file with name
this.importCascadingStyleSheet(this.libPath + "/style/" + fileName + ".css", function(){
callback();
});
}
this.importSource = function(fileName, callback){ // import script with name
this.importScript(this.libPath + "/client/" + fileName + ".js", function(){
callback();
});
}
var me = this;
me.libPath = me.getLibPath();
me.importStyle("myCssFile", function(){
me.importSource("firstCodeFile", function(){
me.importSource("secondCodeFile", function(){
me.importSource("thirdCodeFile", function(){
// ... Execute Script code here
var foo = new Bar();
})
})
})
});
状态。
我该如何解决？
