Question

in order to set the selected option by value for a html select with jquery
i do this as follows:

 $('#mySelectId option[value="avancement d\'échelon"]').attr("selected","selected");

is the problem because my string value contains ' ?

Answer 1

Use

$('#mySelectId option[value="avancement d\'échelon"]').attr("selected", true);

instead.

Also to remove the selected attribute use

$('#mySelectId option[value="avancement d\'échelon"]').attr("selected", false);
