一些JQuery插件不只是向DOM节点添加行为,而是更改它们.例如,Bootstrap Switch转向
<input type="checkbox" name="my-checkbox" checked>
变成类似的东西
<div class="bootstrap-switch bootstrap-switch-wrapper bootstrap-switch-on bootstrap-switch-large bootstrap-switch-animate">
<div class="bootstrap-switch-container">
<span class="bootstrap-switch-handle-on bootstrap-switch-primary">ON</span>
<label class="bootstrap-switch-label"> </label>
<span class="bootstrap-switch-handle-off bootstrap-switch-default">OFF</span>
<input type="checkbox" name="download-version" checked="" data-size="large" data-on-text="3" data-off-text="2.0.1">
</div>
</div>
同
$("[name='my-checkbox']").bootstrapSwitch();
哪个与React不相符:
Uncaught Error: Invariant Violation: findComponentRoot(..., .0): Unable to find
element. This probably means the DOM was unexpectedly mutated (e.g., by the
browser), usually due to forgetting a <tbody> when using tables or nesting <p> or
<a> tags. ...<omitted>...`.
是否有推荐的技术将这些插件合并到React组件中？或者它们是否从根本上打破了React的假设并且无法使用它？
触发AJAX GET以http://qualifiedlocalhost:8888/resource.json启动预期的CORS预飞行,看起来它正确回归:

它应该工作,对吗？
但随后的请求仍然失败并出现错误 XMLHttpRequest cannot load http://qualifiedlocalhost:8888/resource.json. Origin http://localhost:9000 is not allowed by Access-Control-Allow-Origin.

Origin:http://localhost:9000 …IntelliJ附带的JetGradle插件显示我的项目存在冲突.它说我的IDE语言级别是1.7,而我的Gradle语言级别是1.6.
以下代码为所有内容打印1.7:
compileJava {
println project.sourceCompatibility
println project.targetCompatibility
println sourceCompatibility
println targetCompatibility
}
从命令行运行Gradle工作正常.在IDEA中运行它也可以.这两个都使用1.7 JDK.我的IDEA项目和模块也配置为使用1.7.
当我通过Gradle构建脚本导入项目时,版本默认为1.6.我已将其更改为1.7.
什么是"Gradle语言级别",如何修改它？
谢谢!
编辑:我应该已经提到过这个,但我在服务中运行此代码.整个应用程序由小部件按钮打开/关闭,没有任何活动.
更新:我尝试将SDK源附加到项目中,这样我就可以更准确地了解发生故障的位置,但从外观来看,只包含公共API,这似乎使它们的用处更少.任何人都可以建议至少一种调试方法来解决这个问题吗？我有点卡住了.
我正在尝试使用Android的语音识别软件包来记录用户语音并将其翻译成文本.不幸的是,当我尝试启动监听时,我收到的ANR错误并未指出任何具体内容.
正如SpeechRecognizer API指示的那样,如果您尝试从主线程调用它,则抛出RuntimeException.这会让我想知道处理是否过于苛刻......但我知道其他应用程序使用Android API就可以实现这一目的,而且它通常非常活泼.
java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread
这是我试图从我的服务中调用的代码的一个(修剪过的)示例.这是正确的方法吗？
感谢您抽出宝贵时间提供帮助.这是一个我无法克服的障碍.
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
"com.domain.app");
SpeechRecognizer recognizer = SpeechRecognizer
.createSpeechRecognizer(this.getApplicationContext());
RecognitionListener listener = new RecognitionListener() {
@Override
public void onResults(Bundle results) {
ArrayList<String> voiceResults = results
.getStringArrayList(RecognizerIntent.EXTRA_RESULTS);
if (voiceResults == null) {
Log.e(getString(R.string.log_label), "No voice results");
} else {
Log.d(getString(R.string.log_label), "Printing matches: ");
for (String match : voiceResults) {
Log.d(getString(R.string.log_label), match); …我的构建脚本遇到错误（如下）。有没有办法使用与调用 Java 相同类型的输出来运行 Gradle -verbose:class？
有问题的错误，如果有人有一些输入：
Caused by: org.gradle.api.artifacts.ResolveException: Could not resolve all dependencies for configuration ':Project:compile'.

... more
Caused by: java.lang.LinkageError: loader constraints violated when linking org/apache/ivy/core/module/descriptor/DependencyDescriptor class
我有类似的东西
zoomable
.call(d3.zoom()
.scaleExtent([1, Infinity])
.translateExtent([[0, 0], [width, height]])
.on('zoom', handleZoom))
我似乎无法直接调用translateBy的缩放行为,还有其他一些方法来应用translateBy吗？
有没有一种简单的方法可以用 Handlebars 构建字符串“{value}”？也许类似于：
Handlebars.compile("\{{{var}}\}")({var:"value"})
