I have the following HTML:
<img id="unique.name.status" class="icon" src="OffStatus.png" alt="OFFLINE" />
At some point a client refreshes and I may need to change the image src
and alt
with id 'unique.name.status'. First, however, I must be able to find the specific image and, currently, I'm getting an undefined
value with the following code:
statusimageId = "#" + user_id + ".status";
alert(statusimageId); // confirmed valid: '#unique.name.status'
statusimageSource = $(statusimageId).attr("src"); // returns 'undefined'
alert(statusimageSource);
NOTE: user_id
is a value returned from JSON
jQuery treats its selectors like CSS. Thus, if your statusimageId
looks like #USERID.status
, then jQuery is looking for the element with ID "USERID" and class "status". You'll want to use a different convention than .
to add your "status" flag. Try:
<img id="unique_name_status" class="icon" src="OffStatus.png" alt="OFFLINE" />
and
statusimageId = "#" + user_id + "_status";
