嘿,我正在开发一个使用PDO和MySQL数据库列出车辆数据的站点。包含某些类字符串的jQuery显示元素
这里是什么,我现在有一个例子:http://www.drivencarsales.co.uk/
所以基本上在MySQL表的每一行包含所有数据的每辆车,我使用下面的代码打印它们放入一个列表:
<?php include('db-affinity/filter.php'); ?>
<div class="col-md-8 col-sm-8 col-lg-8">
<?php while($row = $results->fetch(PDO::FETCH_ASSOC))
{
echo '
<div class="listing-container ' . $row["Make"] . '">
<a href="carpage.php"><h3 class="model-listing-title clearfix">'.$row["Make"].' '.$row["Model"].' '.$row["Variant"].'</h3></a>
<h3 class="price-listing">£'.number_format($row['Price']).'</h3>
</div>
<div class="listing-container-spec">
<img src="'.(explode(',', $row["PictureRefs"])[0]).'" class="stock-img-finder"/>
<div class="ul-listing-container">
<ul class="overwrite-btstrp-ul">
<li class="diesel-svg list-svg">'.$row["FuelType"].'</li>
<li class="saloon-svg list-svg">'.$row["Bodytype"].'</li>
<li class="gear-svg list-svg">'.$row["Transmission"].'</li>
<li class="color-svg list-svg">'.$row["Colour"].'</li>
</ul>
</div>
<ul class="overwrite-btstrp-ul other-specs-ul h4-style">
<li>Mileage: '.number_format($row["Mileage"]).'</li>
<li>Engine size: '.$row["EngineSize"].'cc</li>
</ul>
<button href="#" class="btn h4-style checked-btn hover-listing-btn"><span class="glyphicon glyphicon-ok"></span> History checked
</button>
<button href="#" class="btn h4-style more-details-btn hover-listing-btn tst-mre-btn"><span class="glyphicon glyphicon-list"></span> More details
</button>
<button href="#" class="btn h4-style test-drive-btn hover-listing-btn tst-mre-btn"><span class="test-drive-glyph"></span> Test drive
</button>
<h4 class="h4-style listing-photos-count"><span class="glyphicon glyphicon-camera"></span> 5 More photos</h4>
</div>
';
} ?>
</div>
</div>
</div>
<script>$(“.select-box”).change(function() {
// get the value of the select element
var make = $(this).val();
//get all of the listing-container divs, remove the ones with the selected make class, then hide the rest
$(“.listing-container”).not(“.” + make).hide();
});</script>
正如你所看到的,我正在使用while循环来显示每一行,我还将车辆的'Make'添加到列表容器类,但也有一些jQuery,但我会解释它是什么马上使用。
我再有这样的形式:
<div class="container con-col-listing">
<div class="row">
<div class="col-md-4 col-sm-4">
<form class="car-finder-container dflt-container">
<h2 class="h2-finder">Car finder</h2>
<ul class="toggle-view">
<li class="li-toggle">
<h4 class="h4-finder-toggle">Make<span class="glyphicon glyphicon-plus glyph-plus-toggle"></span></h4>
<div class="panel">
<select class="form-control select-box" name="">
<option value="make-any">Make (Any)</option>
<?php while($make = $filterres->fetch(PDO::FETCH_ASSOC))
{
echo '
<option value="">'.$make["Make"].'</option>
';
} ?>
</select>
<select class="form-control last-select select-box">
<option value="model-any">Model (Any)</option>
<option value="two">Two</option>
<option value="three">Three</option>
<option value="four">Four</option>
<option value="five">Five</option>
</select>
</div>
</li>
<li class="li-toggle">
<h4 class="h4-finder-toggle">Body type<span class="glyphicon glyphicon-plus glyph-plus-toggle"></span></h4>
<div class="panel">
<input id="four-by-four-checkbox" class="float-checkbox" type="checkbox"/>
<label for="four-by-four-checkbox" class="label-checkbox">4x4</label>
<input id="convertible-checkbox" class="float-checkbox" type="checkbox"/>
<label for="convertible-checkbox" class="label-checkbox">Convertible</label>
<input id="coupe-checkbox" class="float-checkbox" type="checkbox"/>
<label for="coupe-checkbox" class="label-checkbox">Coupe</label>
</div>
</li>
<li class="li-toggle">
<h4 class="h4-finder-toggle">Transmission<span class="glyphicon glyphicon-plus glyph-plus-toggle"></span></h4>
<div class="panel">
<input id="automatic-checkbox" class="float-checkbox" type="checkbox"/>
<label for="automatic-checkbox" class="label-checkbox">Automatic</label>
<input id="manual-checkbox" class="float-checkbox" type="checkbox"/>
<label for="manual-checkbox" class="label-checkbox">Manual</label>
<input id="semi-auto-checkbox" class="float-checkbox" type="checkbox"/>
<label for="semi-auto-checkbox" class="label-checkbox">Semi automatic</label>
</div>
</li>
</ul>
<button href="#" class="btn btn-block car-search-button btn-lg btn-success"><span class="glyphicon car-search-g glyphicon-search"></span> Search cars
</button>
<h4 class="h4-finder"><a href="#">Try our Smart Search </a><span class="glyphicon info-car-search-g glyphicon-info-sign"></span></h4>
</form>
</div>
你只需要采取通知的形式开始,你可以看到“制作的”车辆都显示在使用选择元素选项while循环。
现在回到了jQuery:
<script>$(“.select-box”).change(function() {
// get the value of the select element
var make = $(this).val();
//get all of the listing-container divs, remove the ones with the selected make class, then hide the rest
$(“.listing-container”).not(“.” + make).hide();
});</script>
我曾尝试加入这个jQuery来显示显示在选择元素的选项中选择相同的“制作”的课程,并隐藏不包含类该列表容器div中的那个类。
由于某些原因,当选择该选项时,jQuery没有显示与选定选项具有相同'Make'的类。
任何想法我错了?
顺便说一句我知道我应该使用AJAX,但我不知道从哪里开始。
好像你应该选择父和应用不是。 '$('PARENT_CONTAINER_SELECTOR')。children()。not('。'+ make)。hide();' – 2014-09-22 16:44:15
