? 對(duì)于C/S模式下的對(duì)話框彈出問(wèn)題就不說(shuō)了,這里只討論B/S模式下的實(shí)現(xiàn).
? 開(kāi)發(fā)環(huán)境是:struts+hiberinate+spring
??遇到的問(wèn)題是在JSP頁(yè)面新增成功后彈出新增成功的提示對(duì)話框.
? 剛開(kāi)始覺(jué)得在JAVA中很不容易實(shí)現(xiàn),因?yàn)橐郧皩慍#時(shí)習(xí)慣了一種寫法:Response.Write("<script>alert('say what you want to say');</script>");但在JAVA中我卻不知道在action中去怎么寫出這樣的代碼了.為此感覺(jué)不好做,但又不得不做,所以就只有想另外一種辦法了.問(wèn)題是解決了,但總感覺(jué)有些郁悶,為什么不可以更簡(jiǎn)單的實(shí)現(xiàn)呢?
??? 下面是我實(shí)現(xiàn)的過(guò)程.JSP頁(yè)面加了一個(gè)<html:hidden property="propertyName" />,然后就是新增操作的action對(duì)應(yīng)的form的后臺(tái)代碼中加了變量propertyName和與此對(duì)應(yīng)的getter和setter屬性,這樣在action中當(dāng)新增成功后就通過(guò)form中的setter屬性對(duì)字段賦值.然后通過(guò)腳本來(lái)取得JSP頁(yè)面上的隱藏控件(<html:didden/>)的value.這樣做判斷就可以實(shí)現(xiàn)了.
? 也不知道大家都有什么好的方法,希望貼出來(lái)學(xué)習(xí)一下.
???下邊是部分代碼:
???action部分代碼:
???? public ActionForward sumbit(ActionMapping mapping,
??????....
????? if (isAdd) {
??????? bookVhlForm.setBookNo(bookNo);
??????? bookVhlForm.reset(mapping,request);
??????? this.saveErrors(request, errors);
??????? return mapping.findForward("bookVehicle");
????? }
??????...
???????return mapping.findForward("bookVehicle");
?????}
???actionForm部分代碼:
??????package com.portal.web.vehicleManage.form
?????????import org.apache.struts.action.*;
?????????import javax.servlet.http.*;
?????????public class BookVhlForm??? extends ActionForm {
?????????...
?????????private String bookNo;
?????????....
?????????public String getBookNo() {
?????????????return bookNo;
????????}
????????public void setBookNo(String bookNo) {
????????? this.bookNo = bookNo;
??????? }
???JSP腳本:
??????function bookNo(){
??????????var bookNo=document.all("bookNo").value;?
??????????if(bookNo!=""){?
????????????alert("您的預(yù)約登記已申請(qǐng)成功,預(yù)約登記號(hào)為:"+ bookNo);?
??????????} else{?
????????????alert("do the operate which you want!");
???????????}?
