[英]Select2 Placeholder not working
I'm trying to use the Select2 multiple placeholder. 我正在尝试使用Select2多个占位符。 And when I use it, its simply not working.
当我使用它时,它根本无法正常工作。
this is my JS code: 这是我的JS代码:
$(".materialS").select2({
placeholder: 'Material types'
});
and the Html/Php code: 以及Html / Php代码:
<select class="materialS" name="material[]" multiple="multiple">
<?php if ($materials){
foreach ($materials as $material) { ?>
<option value="<?php echo safe_class($material)?>"><?php echo $material; ?></option>
<?php }} ?>
</select>
so I get the materials from db(more like wp). 所以我从db获得资料(更像wp)。 now the thing is that when I click on some select and then I remove it, I can see the placeholder but not before.
现在的问题是,当我单击某些选择然后将其删除时,可以看到占位符,但之前看不到。
any idea whats wrong? 你知道怎么了吗?
Dom is not ready when javascript script is executed. 执行JavaScript脚本时,Dom尚未就绪。
try including this code inside document.ready https://learn.jquery.com/using-jquery-core/document-ready/ 尝试在document.ready https://learn.jquery.com/using-jquery-core/document-ready/中包含此代码
$(function() {
$(".materialS").select2({
placeholder: 'Material types'
});
});
