php - 使用ajax php mysql实现分页搜索

Question

大家好，我正在尝试使用 ajax、php、mysql、jquery 在网站中实现搜索功能。现在，当我转到列表页面(网站上包含项目列表的页面)。但我在索引页上进行了搜索，其结果必须显示在列表页上。基本分页是使用 php 完成的，适用于来自菜单的链接，但搜索失败。(即，如果使用搜索查询从索引页面重定向，则它不起作用)

搜索文本框:

        <form name="homePageSearchForm" method="post" action="cities.php" autocomplete="off">
                 <!--   <input type="hidden" value="e.g kolte patil life republic, wagholi pune" id="hiddenExData" name="hiddenExData">-->
                    <div style="padding-top:5px; line-height:20px; width:280px;" class="flt">
                    <div class="flt"><strong>Locality, City, Builder or Project name</strong><span style="color:#FF3300;">*</span><br>
                    <div class="flt"><input type="text" onBlur="if(this.value=='') this.value='e.g kolte patil life republic, wagholi pune';" onFocus="if(this.value=='e.g kolte patil life republic, wagholi pune') this.value='';" value="e.g kolte patil life republic, wagholi pune" name="SearchValue" id="searchId" title="Search" class="headerinput ac_input" autocomplete="off">

列出必须显示内容的页面 div。

            <div class="flt width710" id="displayProp">
            <div style="margin-top:10px;" class="flt mapnewalert"> <?php //echo ucfirst($_SESSION['$city']) ?></div>
            <div style="float:right" id="toppagesel">
            <?php 
                    echo $pages->display_pages();
                    echo $pages->display_items_per_page();
                /*  if(isset($localitySearch) && $localitySearch!='' && isset($citySearch) && $citySearch!='')
                    {
                        $query = "SELECT * from properties inner join cities on properties.city_id=cities.city_id inner join locality on properties.locality_id=locality.locality_id where (cities.city_name like '%".$citySearch."%' and locality.locality_name like '%".$localitySearch."%') and (property_price_min between '78 Lacs' and '80 Lacs') $pages->limit";
                    }*/

                //  else
                //  {
                    $query = "SELECT * from properties,locality,cities where properties.city_id='".$_SESSION['$cityId']."' and properties.locality_id=locality.locality_id and properties.city_id=cities.city_id $pages->limit";
                //  }

                //  echo $query;
                    $result = mysql_query($query) or die(mysql_error());

                    //$getProperty =    $propertyDetails->getPropertyDetailsByCityIdPaginate($_SESSION['$cityId'],$limit);
            ?>
            <?php //echo $pages->display_pages(); ?><?php //echo $pages->display_items_per_page();?>
            </div>
        </div>

现在点击搜索按钮我调用一个 javascript 函数如下

                   <input type="submit" onClick="**handleHomePageSearch(0,'e')**;return false;" value="SEARCH" class="hpnewsubmitbtn">

js函数:

             function handleHomePageSearch(buttonEle,e) {
             var criteria  = document.getElementById("searchCriteria").value;
            var searchVal = document.getElementById("searchId").value;
            xmlHttpSearchct=GetXmlHttpObject();
            var cur_page = document.getElementById("current_page").innerHTML;

            var url="fetchCity.php?&searchVal="+searchVal+"&buttonEle="+buttonEle+"&cur_page="+cur_page;
            alert(url);
            xmlHttpSearchct.open("GET",url,false);

            xmlHttpSearchct.send(null);

                           var Searchres=xmlHttpSearchct.responseText;
                       **//To get the response**
                        xmlhttp.onreadystatechange=function()
          {
              if (xmlhttp.readyState==4 && xmlhttp.status==200)
                {
                                    document.getElementById('displayProp').innerHTML=Searchres;
                }
          }

这会以 HTML 的形式返回响应，但我无法在列表 (properties.php) 页面上显示它。此外，如果我使用搜索值，分页也不起作用。

fetchCity.php 包含搜索查询和返回数据的 HTML。

                   $searchValue= $_GET['searchVal'];
$buttonEle  = $_GET['buttonEle'];
$current_page=$_GET['cur_page'];

    $locCity = explode(" ",$searchValue);
    $localitySearch =   $locCity[0];
    $citySearch     =    $locCity[1];

        $query = "SELECT * from properties inner join cities on properties.city_id=cities.city_id inner join locality on properties.locality_id=locality.locality_id where (cities.city_name like '%".$citySearch."%' and locality.locality_name like '%".$localitySearch."%') and (property_price_min between '78 Lacs' and '80 Lacs') $pages->limit";
    //echo $query;
    exit;
    $result = mysql_query($query) or die(mysql_error());

我想知道我的方法是否正确？如何在分页工作的情况下在另一个页面上显示搜索结果。

为了引用，我将添加具有类似功能的引用站点的链接。

Answer 1

$(document).ready(function () {
    $('.paginate').live('click', function (e) {
        e.preventDefault();
        var btnPage = $(this);
        $.ajax({
            url: btnPage.attr('href'),
            success: function (resp) {
                // replace current results with new results.
                $('#project_section').html(resp);
            },
            error: function () {
                window.location.href = btnPage.attr('href');
            }
        });
    });
});

这里 $(".paginate") 是 <li> 的类在我的分页器类中。我得到了答案here谢谢
