在Chrome移动浏览器上，keypress/keyup不起作用 [英] keypress/keyup is not working on chrome mobile browser

问题描述

我一直在基于Web的Asp.net MVC应用程序中使用jquery，当我使用chrome mobile测试我的工作时，我发现基于keypress/keyup的jquery功能不起作用.

I have been using jquery in my web based Asp.net MVC application, and when i use chrome mobile to test my work i found that jquery's functions which are based upon keypress/keyup is not working.

我不知道为什么它不能在移动浏览器上运行.它可以在桌面浏览器上正常工作.

I didn't know why it is not working on mobile browsers. It is working properly on desktop browsers.

任何人都可以解决我的问题，在此先感谢.

Can anyone solve my problem, thanks in advance.

This worked for me: http://www.dotnetfunda.com/forums/show/8137/onkeyup-event-not-firing-in-firefox-and-chrome

代码:

<textarea name="textarea" id="txtComments" rows="3" onkeyup='return fnMaxLength(this,"5");' style="width: 940px" ></textarea> 

函数fnMaxLength(field，maxChars){

function fnMaxLength(field, maxChars) {

if (field.value.length >= maxChars) { 

    var object = "-More than " + maxChars + " characters have been entered.";

    //errorAlert("error", "Maximum length error", object);

    alert(object);

    return false; 

} 

}
