Jquery Find a specific class with a specific attribute value

Question

I currently have something like this in my code

<input class="parameterValueInput" trigger="@item.Name">

What I would like to do is to change content of an input that has a class name parameterValueInput and attribute called trigger with value "triggerValue"; I am not sure how to write a selector for that. any suggestions ?

You can try like this :

$("input[class=parameterValueInput][trigger=triggerValue]").focus()

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<input class="parameterValueInput" trigger="triggerValdue">
<input class="parameterValueInput" trigger="triggerValu2e">
<input class="parameterValueInput" trigger="triggerValue">

As , @mplungjan said in comment to use $("input.parameterValueInput[trigger=triggerValue]") if you have mutliple class else if only one class use above .

$("input.parameterValueInput[trigger=triggerValue]") is likely more safe

Your selector will fail on <input class="parameter parameterValueInput"

@mplungjan yes you are right :) Thank you for suggestion . I have added your suggestion in my answer .

ALWAYS use .class EVEN if you have one class, since it takes only a second to add a class and break the script. That can be added even from another part of the script so NEVER use class=someClass over .someClass
