ulengthvalidator.java

这个是使用java开发的一个平台

package com.exp.web.util.validator;

import com.exp.fcl.xml.EXPXMLNode;
import com.exp.web.util.FormBean;

public class ULengthValidator extends BaseValidator {
    protected int min = -1;

    protected int max = -1;

    protected void initConfig(EXPXMLNode validator) {
        String temp = validator.getAttributeValue("min");
        if (!temp.equals("")) {
            this.min = Integer.valueOf(temp).intValue();
        }
        temp = validator.getAttributeValue("max");
        if (!temp.equals("")) {
            this.max = Integer.valueOf(temp).intValue();
        }
    }

    public boolean checkValid(FormBean formBean) {
        String value = formBean.getString(this.getTarget());
        if (min != -1) {
            if (value.length() < min) {
                return false;
            }
        }
        if (max != -1) {
            if (value.length() > max) {
                return false;
            }
        }
        return true;
    }

    protected String genCheckCondition() {
        StringBuffer buf = new StringBuffer();
        buf.append("if(");
        buf.append("!limit(");
        buf.append(this.getTargetValueWithForm());
        buf.append(",");
        buf.append(this.min);
        buf.append(",");
        buf.append(this.max);
        buf.append(")");
        buf.append(this.getEmptyJumpScript());
        buf.append(" )");
        return buf.toString();
    }
