输入按键按下javascript功能

Question

I have an asp:TextBox on my page and I would like to detect the enter key to call a javascript function. This is what I have:

Codebehind

txtSearch.Attributes.Add("OnKeyPress", "ProcessKeyPressed()")

aspx page

 function ProcessKeyPressed() {
    if (event.keyCode == 13 || event.keyCode == 10 ) {
        Search();
    }
 }

This works in chrome and IE, but not in Firefox...any idea why this might be the case?

Thanks in advance,

Try:

function ProcessKeyPressed(event) {
   if (event.keyCode == 13 || event.keyCode == 10 ) {
       Search();
   }
}

Code behind:

txtSearch.Attributes.Add("OnKeyPress", "ProcessKeyPressed(event || window.event)")

And JS:

function ProcessKeyPressed(event) {
    if (event.keyCode == 13 || event.keyCode == 10 ) {
        Search();
    }
 }

Based on this

You may try this

function ProcessKeyPressed(e) {
    var event = e || window.event;
    var key = event.charCode || event.keyCode
    if (key == 13 || key == 10 ) {
        Search();
    }
}
