Textarea.textcontent is not changing

问题

I have a select object whose onChange event is calling this method:

 function universeChange()
 {

var select = document.getElementById("universeSelect");


form = document.getElementById("textAreaUniverse");

//form.textContent = universeDict[select.selectedIndex].value;
form.textAreaValue = universeDict[select.selectedIndex].value;

 }

When I am debugging in developer tools the textContent value changes as it should change but the clients end doesn't reflect the new values. I have this feeling that I am not using the correct method to change the value of the textarea?

回答1:

Have you tried using the .value attribute to change the text?
