Holen Sie sich Text der ausgewählten Option JS
var sel = document.getElementById("box1");
var text= sel.options[sel.selectedIndex].text;
Encouraging Elephant
var sel = document.getElementById("box1");
var text= sel.options[sel.selectedIndex].text;
// Get highlighted text this way:
window.getSelection().toString()<select id="ddlViewBy">
<option value="1">test1</option>
<option value="2" selected="selected">test2</option>
<option value="3">test3</option>
</select>
Running this code:
var e = document.getElementById("ddlViewBy");
var strUser = e.value;
Would make strUser be 2. If what you actually want is test2, then do this:
var e = document.getElementById("ddlViewBy");
var strUser = e.options[e.selectedIndex].text;function disp() {
var text = document.getElementById("text");
var t = text.value.substr(text.selectionStart, text.selectionEnd - text.selectionStart);
alert(t);
}const getSelectedText = () => window.getSelection().toString();
getSelectedText();
