    <p>I am trying to implement a photo gallery(I think all of you already know about it, because i post a lot of questions :) ). If i assign a function in onclick property of a DOM element the function works ok.</p> <pre><code>var img_thumb = document.createElement('img'); img_thumb.src = photos[i].img_thumb; img_thumb.onclick = function showImage(img_thumb) { var index = arr_thumb.indexOf(img_thumb.target); document.getElementById('largeImgPanel').appendChild(arrow_right); document.getElementById('largeImg').src = arr_big[index].src; showLargeImagePanel(); unselectAll(); }; </code></pre> <p>Now this is just functions, if i try to add here same showImage function and call it on click the arrow to change displayed picture it is does not work.</p> <pre><code>function showLargeImagePanel() { document.getElementById('largeImgPanel').style.visibility = 'visible'; } function unselectAll() { if(document.selection) document.selection.empty(); if(window.getSelection) window.getSelection().removeAllRanges(); } </code></pre> <p>I tryed to rewrite it in different ways but there is no changes, if i click the arrow the "largeImagePanel" just closes.</p> <p>Here is my last version of showImage function:</p> <pre><code>function showImage(img_src) { document.getElementById('largeImg').src = img_src; showLargeImagePanel(); unselectAll(); }; </code></pre> <p>Can someone give me any idea about my problem?</p> <p>if i write same property "onclick" to arrow object, the "largeImgPanel" closes again >:</p> <pre><code>arrow_right.onclick = function() { document.getElementById('largeImgPanel').appendChild(arrow_right); document.getElementById('largeImg').src = next; showLargeImagePanel(); unselectAll(); }; </code></pre>

    1. COYou might want to study up on adding event handlers and what those functions supply as arguments (hint: it's an event object).

    3. COIf I understand your question correctly, you are expecting something other than the *browser specified default* to happen when a *click event* is triggered without adding a *click event listener*? Also this is one of those cases where using jQuery or any other JS library might be a good idea..

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
