我使用 GWT 的 htmlflow 在我的代码中添加了一个动态文本框。现在我想从文本框中检索值。下面是代码,任何帮助都会很明显。通过使用 Rootpanel.get(elementID)。我能够得到元素值
运营商/p:
<input id="value1" 80px;="" border:="" 0px;="" border-bottom:="" 4px="" solid="" #3366ff;'="" type="textstyle='width:">
从这里我如何获得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());
}
}
});
