form表单回写技术java实现

本文实例为大家分享了form表单回写技术，供大家参考，具体内容如下

回写支持的java拼js的方法：

 
  public static String writeBackMapToForm(Map mRequest) {
    return writeBackMapToForm(mRequest, new String[]{}, "writeBackMapToForm");
  }
  
  public static String writeBackMapToForm(Map mRequest, String[] ignoreName, String jsFunctionName) {
  mRequest.remove("checkbox_template"); //不回写列表中checkbox的值
    StringBuffer rtValue = new StringBuffer();
    rtValue.append(" var mForm = new Object();n");
    rtValue.append(" var indexArray = new Array();n");
    rtValue.append(" function writeBackMapToForm() {n");
    Iterator itMRequest = mRequest.keySet().iterator();
    while (itMRequest.hasNext()) {
      String tempKey = (String) itMRequest.next();
      Object tempValue = mRequest.get(tempKey);
      if (tempKey.startsWith("VENUS") || tempKey.startsWith("RANMIN")) {
 continue; 
      }
      if (RmStringHelper.ArrayContainString(ignoreName, tempKey)) {
 continue; 
      }
      String tempValueNew = "";
      if (tempValue instanceof String) { //如果是单值，直接注入
 tempValueNew = RmStringHelper.replaceStringToscript((String)tempValue); //从数据库中取出来以后需要转换1次
 rtValue.append("  indexArray[indexArray.length] = "" + tempKey + "";n");
 rtValue.append("  mForm["" + tempKey + ""] = "" + tempValueNew + "";n");
      } else if (tempValue instanceof String[]) { //如果是多值，放入数组
 rtValue.append("  indexArray[indexArray.length] = "" + tempKey + "";n");
 String[] myArray = (String[]) tempValue;
 if ( tempKey.equals("cmd") ){
   tempValueNew = RmStringHelper.replaceStringToscript(myArray[0]);
   rtValue.append("  mForm["" + tempKey + ""] = "" + tempValueNew + "";n");
 } else {
   rtValue.append("  mForm["" + tempKey + ""] = [");
   for (int i = 0; i < myArray.length; i++) {
     if (i > 0)
rtValue.append(",");
     tempValueNew = RmStringHelper.replaceStringToscript(myArray[i]);
     rtValue.append(""" + tempValueNew + """);
   }
   rtValue.append("];n");
 }
      } else if (tempValue instanceof Timestamp) { //如果是时间戳，直接注入
 if(tempValue == null) {
   continue;
 }
 tempValueNew = RmStringHelper.replaceStringToscript(tempValue.toString().substring(0,19));
 rtValue.append("  indexArray[indexArray.length] = "" + tempKey + "";n");
 rtValue.append("  mForm["" + tempKey + ""] = "" + tempValueNew + "";n");
      } else if (tempValue instanceof BigDecimal){
 tempValueNew = RmStringHelper.replaceStringToscript(tempValue.toString());
    rtValue.append("  indexArray[indexArray.length] = ""
 + tempKey + "";n");
    rtValue.append("  mForm["" + tempKey + ""] = ""
 + tempValueNew + "";n");
      } else {
 if(tempValue != null) {
   RmStringHelper.log("在回写页面时，遇到了未知java类型:" + tempValue);   
 }
 continue;
      }
    }
    rtValue.append("  for(var i=0; i
