[英]How to dynamically pass data from PHP to JavaScript (In dynamically created HTML elements)
我有一個從數據庫填充的實體數組,每個實體都有自己的GUID 。 我通過遍歷實體數組並將它們放置在新的動態創建的div
包裝器中,將它們顯示在網頁(HTML)上 。
<?php
$images = elgg_extract('entities', $vars, FALSE);
foreach ($images as $image) {
$img = elgg_view_entity_icon($image, 'small');
$image_guid = $image -> getGUID();
echo <<<HTML
<div class="file-preview-frame">
<div class="image-preview">{$img}</div>
<button type="button" class="btn-default" data-guid={$image_guid}></button>
</div>
HTML;
}
elgg_require_js('js/inline_image_view');
inline_image_view.js
require(['elgg/Ajax'], Ajax => {
var ajax = new Ajax();
$('.btn-default').click(function(event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var recipient = button.data('guid') // Extract info from data-* attributes
ajax.view('albums/inline_full_image_view', {
data: {
guid: recipient // querystring
},
}).then(body => {
$( '.full-image-view' ).html(body);
})
});
});
如何在RequireJS的inline_image_view.js中將每個按鈕單擊與特定圖像的GUID相關聯? 最好的或首選的方法是什么?
謝謝大家?
感謝Elgg社區 ,尤其是Ismayil Khayredinov 。
