本文整理了Java中com.google.gwt.xhr.client.XMLHttpRequest.send()方法的一些代码示例，展示了XMLHttpRequest.send()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。XMLHttpRequest.send()方法的具体详情如下：
包路径：com.google.gwt.xhr.client.XMLHttpRequest
类名称：XMLHttpRequest
方法名：send

XMLHttpRequest.send介绍

[英]Initiates a request with no request data. This simply calls #send(String) with null as an argument, because the no-argument send() method is unavailable on Firefox.
[中]启动没有请求数据的请求。这只是调用带有null作为参数的#send（String），因为在Firefox上没有参数send()方法。
