我已将 Modernizr 安装到我的代码中,以在 firefox 3.6 中启用 html5 占位符支持

我的问题是,因为我使用模板结构 (MVC) 作为我的代码库,我不确定如何让“if()”脚本适用于我的特定页面,因为它必须在视图中调用。我已将modernizr 脚本移至我的haeder -> 在我的页脚中

我的表格:

 <?php
//Setting form attributes
$formAddSale = array('id' => 'addSale', 'name' => 'addSale');
$saleName = array('id' => 'name', 'name' => 'name', 'placeholder' => 'Name*');
$saleLocation = array('id' => 'location', 'name' => 'location', 'placeholder' => 'Location*');
$saleBedrooms = array('id' => 'bedrooms','name' => 'bedrooms', 'placeholder' => 'Number of Bedrooms*');
$saleBathrooms = array('id' => 'bathrooms','name' => 'bathrooms', 'placeholder' => 'Number of Bathrooms*');
$saleCondition = array('id' => 'condition','name' => 'condition', 'placeholder' => 'Condition*');
$saleImage = array('id' => 'userfile', 'name'=> 'userfile', 'placeholder' => 'File Location*');
$saleDescription = array('id' => 'description','name' => 'description', 'placeholder' => 'Sale Description*');
$salePrice = array('id' => 'price','name' => 'price', 'placeholder' => 'Price*');
?>

<section id = "validation"><?php echo validation_errors();?></section>
<?php 
echo form_open_multipart('admin/addsale/', $formAddSale);
echo form_fieldset(); 
echo form_input($saleName);
echo form_input($saleLocation);
echo form_input($saleBedrooms);
echo form_input($saleBathrooms);
echo form_input($saleCondition);
echo form_input($salePrice);
echo form_upload($saleImage);
echo form_textarea($saleDescription);
echo form_submit('submit','Submit');
echo form_fieldset_close();
echo form_close();
?>

在写这个问题的时候,我已经用下面的代码创建了一个“misc.js”文档:

    // if placeholder isn't supported:
if (!Modernizr.input.placeholder){
  // use a input hint script
    setInputHint(document.getElementById('name'),'Name*');
    setInputHint(document.getElementById('location'),'Location*');
    setInputHint(document.getElementById('bedrooms'),'Number of Bedrooms*');
    setInputHint(document.getElementById('bathrooms'),'Number of Bathrooms*');
    setInputHint(document.getElementById('condition'),'Condition*');
    setInputHint(document.getElementById('price'),'Price*');
    setInputHint(document.getElementById('description'),'Sale Description*');
    setInputHint(document.getElementById('userfile'),'File Location*');
   }

我已经像往常一样在我的“模板”的页脚中包含了上述文档

<!-- jQuery Files --> 
<script type="text/javascript"    src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script> 
<script type="text/javascript" src="http://www.domain.co.nz/includes/js/placeholder.js"></script> 
<script type="text/javascript" src="http://www.domain.co.nz/includes/js/misc.js">    </script>

您是否收到任何 Javascript 错误?

因为您使用的是 JS 库 (jQuery),所以您可以将 'document.getElementById' 替换为 '$',从​​而节省大量编码。
