JavaScript gets the selected value in the select tag

Copy the code as follows: var obj = document.getElementById("testSelect"); //Locate id

var index = obj.selectedIndex; // Select index

var text = obj.options[index].text; // Select text

var value = obj.options[index].value; // Select the value

Get selected select value in jQuery

The first method

The code copy is as follows: $('#testSelect option:selected').text();//Selected text

$('#testSelect option:selected').val();//The selected value

$("#testSelect").get(0).selectedIndex;//Index

The second way

The code copy is as follows: $("#tesetSelect").find("option:selected").text();//Selected text

$("#tesetSelect").find("option:selected").val();

$("#tesetSelect").find("option:selected").get(0).selectedIndex;

The above is all the content of JavaScript to obtain the selected value selected by the select tag. I hope it can give you a reference and I hope you can support Wulin.com more.
