Jquery Selector optimization for multiple clicks
Your second selector doesn't work with the data provided input:tel#8888 is not the id= of the input.  

IDs should start with a letter (for compatibility), so if you changed your input to &lt;input id="inp8888"&gt; then you could use input:tel#inp8888 in which case, you can use $("#inp8888") as long as your IDs are unique (which they should be).

Selecting by ID is the fastest selection method. 


  jQuery uses document.getElementById(), which is faster
