How to resolve Invalid Query selector when dynamically generating ID in .net












0















I am trying to access an element using id.



The catch is as follows:




  • I am generating the id using razor Syntax.

  • I am then passing the string as parameters to a function.

  • In that function I am using document.Query("#id") selector.


My function:



 function upload(x , y, z  ) {



            var selector = """ + "#" + z + x + """;

            console.log(selector);

            var form = document.querySelector(selector);

                var formData = new FormData(form);

 ...}



 The console.log() is correct.



It shows "#a1.3"




which is the id of the dynamically generated HTML element. Just to be sure,I removed special characters from id and gave just characters.



But I still get the same error.



I have no clue why it might be happening.

    Is the id "#a1.3" a valid id? maybe you meant to say #a1.3 without the double quotes. var selector = "#" + z + x;

You need to escape the period in that selector...



"#a1\.3"

            Run scheduled task as local user group (not BUILTIN)

            0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
