我使用GWT的htmlflow为我的代码添加了一个动态文本框。现在我想从文本框中检索值。以下是代码,任何帮助将是可感知的。通过使用Rootpanel.get(elementID)。能够将元素值作为
O / p:
<input id="value1" 80px;="" border:="" 0px;="" border-bottom:="" 4px="" solid="" #3366ff;'="" type="textstyle='width:">
从中我如何掌握我在文本框中输入的值?
String alertText = "If pressure > ? and glucoselevel > ? ";
String newAlertText = alertText.replace("?", "");
numberOfPlaceHolder = alertText.length() - newAlertText.length();
System.out.println("Num of Place holder :"+numberOfPlaceHolder);
String[] alertblock = alertText.split("\\?");
StringBuffer alertHtml = new StringBuffer();
for(int i=1; i<=numberOfPlaceHolder;i++){
String textbox = "<input id='value"+i+"' type=textstyle='width: 80px; border: 0px; border-bottom: 4px solid #3366FF;' />";
String textblock = alertblock[i-1];
alertHtml.append(textblock);
alertHtml.append(textbox);
}
String alertTextHtml = "<div>"+alertHtml.toString()+"</div>";
htmlFlow = new HTMLFlow(alertTextHtml);
alertTextLay.addMember(htmlFlow);
IButton saveAlertBtn = new IButton();
saveAlertBtn.setTitle("Save Alert");
saveAlertBtn.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
// TODO Auto-generated method stub
LinkedHashMap<String, String> alertValueMap = new LinkedHashMap<String, String>();
for(int i=1; i<=numberOfPlaceHolder;i++){
System.out.println(**RootPanel.get("value"+i));**
//System.out.println(DOM.getElementById("value"+i).getInnerText().toString());
}
}
});

我认为你必须使用GWT Dom API获取元素并获取元素的属性
Element yourElement = DOM.getElementById(YOUR_TEXT_INPUT_ELEMENT);
String the TextOfTheInput = yourElement.getAttribute("value");
