在单击按钮之前等待上载完成

我有一个打开的模式允许上传。模态有一个按钮,用于多个上传,文件上传,上传,取消和确定(选择文件后按,单击上传按钮,然后选择确定返回上一个屏幕)。一切正常,但这是一个非角度的应用程序,所以它不是在选择确定之前等待上传完成。我输入了一个browser.driver.sleep,它给了它足够的时间,但我知道这是一个不可靠的解决方案。有关在选择确定之前如何等待上传完成的任何想法?

测试代码:

this.selectsUploadButton = function () {
    this.waitsForElementToBeClickable(uploadButton);
    uploadButton.click().then(function () {
        browser.driver.sleep(5000);
        uploadButtonOkLogo.click();
    });
};

html:由于叠加,我得到的错误无法点击。

<div id="uploadLogoDialog" class="modal-dialog" style="display: block;">
  <div class="upload-overlay"></div>
  <div class="upload-logo-container">
    <div class="upload-logo-header">Image must be under 50 MB and in the following formats: .JPG, .GIF, .PNG</div>

此处的最佳选择是等待上传按钮使用量角器与disabled对象一起使用的wait()函数获取ExpectedConditionswait()函数总是等待,直到给定的条件为真,所以你必须提供一个参数,使它在某个时间后变为真(这应该是你想要的值)。这是如何 -

var EC = protractor.ExpectedConditions;
browser.wait(EC.not(EC.elementToBeClickable(uploadButton)),10000).then(function(){
    uploadButtonOkLogo.click();
}); //Wait until element is not clickable (checks if element is enabled to decide if its clickable)

或者,您可以编写自己的ExpectedCondition,直到元素未启用,然后在wait函数中使用它。这是如何 -

browser.wait(function(){
    return uploadButton.isEnabled().then(function(enabled){
        return enabled === false;  // wait until element is disabled and if it is disabled then return true
    });
}, 10000).then(function(){
    uploadButtonOkLogo.click();
});

另一种方法是等到上传进度条达到100%,方法是手动编写自己的ExpectedCondition等待。这是如何 -

browser.wait(function(){
    return $('.percentage').getText().then(function(percent){
        return percent === '100 %'; //return true only if percentage is 100%
    });
}, 10000).then(function(){
    uploadButtonOkLogo.click();
});

希望它有所帮助。
