Copy code The code is as follows: <br>$(function () { <br>$('input:text:first').focus(); //Put focus on the first text box<br>var $inp = $('input' ; 🎜> var key = e.which; //e.which is the value of the key<br> if (key == 13) {<br> alert("aaa");<br> }<br>}); <br>});<br><br><br> </div>A strange phenomenon: <p>I dragged a Login control and then converted it into a template for custom development. <br><br><br><br><img src="http://files.jb51.net/file_images/article/201405/20140511111529.png" alt="Jquery monitors keys and presses the Enter key to trigger the implementation code of a method_jquery" ><br> <br>The above code captures the Enter button in the text field. At this time, the LoginButton needs to be triggered to submit the login information for verification. However, use $("[id$=LoginButton]").click(); only on firefox. It works, but it doesn't work in IE. Try $("[id$=LoginButton]").focus();, it works in IE. On IE, focus() completes the focusing and clicks. Why? Woolen cloth? </p> <p></p> <p></p> <div class="codetitle"><span>Copy code<a style="CURSOR: pointer" data="61772" class="copybut" id="copybut61772" onclick="doCopy('code61772')"><u></u> The code is as follows:</a></span></div>$inp.keypress(function (event) {<div class="codebody" id="code61772"> var key = event.which;<br> if (key == 13) {<br> $("[id$=LoginButton]").click(); //Support firefox, IE martial arts school<br> / /$('input:last').focus();<br> $("[id$=LoginButton]").focus(); //Supports IE, firefox is invalid. <br>//The above two sentences are implemented.
