phpcms表单修改版(基于后台表单+前端表单、jsonp、ajax方式实现)

说明(不会phpcms的别看):

(1)表单建立完成后,可以使用ajax,jsonp,form方式来提交信息(三种方式任选其一)
(2)c=forms(这里控制器修改为forms,不是index)

(1)使用form方式

demo:

    <form action="/index.php?m=formguide&c=forms&a=show&formid=13&action=js&siteid=1" method="post">
        您的姓名:<input type="text" name="info[you_name]"  value="" />
        您的手机号:<input type="text" name="info[you_tel]" value="" />
        <select name="info[you_province]" >
             <option value="您所在的省份">您所在的省份:</option>
            <option value="北京">北京</option>
             <option value="上海">上海</option>
        </select>
        <input class="zg_sub" type="submit" id="dosubmit" value="提交信息" />
    </form>

(2)使用jsonp方式

demo(html): 修改提交按钮修改为button

        您的姓名:<input type="text" id="you_name"  value="" />
        您的手机号:<input type="text" id="you_tel" value="" />
        <select id="you_province" >
             <option value="您所在的省份">您所在的省份:</option>
            <option value="北京">北京</option>
             <option value="上海">上海</option>
        </select>
        <input class="zg_sub" type="button" id="dosubmit" value="提交信息" />

demo(js): 修改提交按钮修改为button

    $(function (){
        $("#dosubmit").click(function(event) {
             //表单地址(注意将action值修改为jsonp)!!!!!
            var url = '/index.php?m=formguide&c=forms&a=show&formid=25&action=jsonp&siteid=1';
             //定义info对象并赋值
            var info = {}; 
            info.you_name = $("#you_name").val();
            info.you_tel = $("#you_tel").val();
            info.you_province = $("#you_province option:selected").val();
            //发送ajax(注意使用get请求,dateType为jsonp)
            $.ajax({
                url: url,
                type: 'GET',
                dataType: 'jsonp',
                data: {info: info},
                success:function (json)
                {
                    if (json.status==1) {
                          //json.status为1代表正确(以下的无用,不用看)
                        $("#myform").hide();
                        $(".zg_form img").show();
                        setTimeout(function() {
                            $(".zg_bdbox").hide();
                            $(".zg_btnbox").show();
                            return false;
                            sec++;
                        },3000)
                    } else {
                        alert('失败');
                    }
                }
            })
        });
    })

(3)使用普通ajax方式提交

demo(html): 修改提交按钮修改为button

        您的姓名:<input type="text" id="you_name"  value="" />
        您的手机号:<input type="text" id="you_tel" value="" />
        <select id="you_province" >
             <option value="您所在的省份">您所在的省份:</option>
            <option value="北京">北京</option>
             <option value="上海">上海</option>
        </select>
        <input class="zg_sub" type="button" id="dosubmit" value="提交信息" />

demo(js): 修改提交按钮修改为button

    $(function (){
        $("#dosubmit").click(function(event) {
             //表单地址(注意将action值修改为json)!!!!!
            var url = '/index.php?m=formguide&c=forms&a=show&formid=25&action=json&siteid=1';
             //定义info对象并赋值
            var info = {}; 
            info.you_name = $("#you_name").val();
            info.you_tel = $("#you_tel").val();
            info.you_province = $("#you_province option:selected").val();
            //发送ajax(注意使用get请求,dateType为jsonp)
            $.ajax({
                url: url,
                type: 'GET',
                dataType: 'jsonp',
                data: {info: info},
                success:function (json)
                {
                    if (json.status==1) {
                          //json.status为1代表正确(以下的无用,不用看)
                        $("#myform").hide();
                        $(".zg_form img").show();
                        setTimeout(function() {
                            $(".zg_bdbox").hide();
                            $(".zg_btnbox").show();
                            return false;
                            sec++;
                        },3000)
                    } else {
                        alert('失败');
                    }
                }
            })
        });
    })
