    <p>If you mean like:</p> <pre><code>var elementArray = document.getElementsByName("/regexhere/"); </code></pre> <p>then no that would not be possible.</p> <p>To do what you want to do you would have to get all the elements, then go through each one and check the name of it.</p> <p>Heres a function that will go through all the elements and add all the elements with a certain name to an array:</p> <pre><code> function findElements(name) { var elArray = []; var tmp = document.getElementsByTagName("*"); var regex = new RegExp("(^|\\s)" + name + "(\\s|$)"); for ( var i = 0; i &lt; tmp.length; i++ ) { if ( regex.test(tmp[i].name) ) { elArray.push(tmp[i]); } } return elArray; } </code></pre> <p>And use as:</p> <pre><code>var elName = "customcontrol"; var elArray = customcontrol(elName); </code></pre> <p>Or it might be easier by className</p> <pre><code> function findElements(className) { var elArray = []; var tmp = document.getElementsByTagName("*"); var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)"); for ( var i = 0; i &lt; tmp.length; i++ ) { if ( regex.test(tmp[i].className) ) { elArray.push(tmp[i]); } } return elArray; } </code></pre> <p>And use as:</p> <pre><code>var elClassName = "classname"; var elArray; if (!document.getElementsByClassName) { elArray= findElements(elClassName ); } else { elArray = document.getElementsByClassName(elClassName); } </code></pre> <p>This would do what you want, without the need for getElementByName.</p> <p>Although I think you meant getElementsByName</p> <p>If you wanted to look for an element with only the name "customcontrol" you would use:</p> <pre><code>var regex = new RegExp("(^|\\s)" + name + "(\\s|$)"); </code></pre> <p>If you wanted to look for an element with that STARTED with the name "customcontrol" you would use:</p> <pre><code>var regex = new RegExp("(^|\\s)" + name); </code></pre> <p>EDIT:</p> <p>If your using jQuery, which would be easier, then this would do:</p> <pre><code>var elArray = $("*[name^='customcontrol']"); //Use JavaScript to loop through for (var a = 0; a&lt; elArray.length;a++) { //Loop through each element alert(elArray[a]); } //Or $("*[name^='customcontrol']").css("color","red"); //Or whatever you want to do to the elements </code></pre>

Querying!

 
Guidance
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.

SQuiL has stopped working due to an internal error.

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