C#: How to prevent a textbox' content from being scrolled up on Enter?

阅读更多关于 C#: How to prevent a textbox' content from being scrolled up on Enter?

问题 I'm trying to resize at run-time a textbox' height when the user presses the "Enter" key. The resizing works well, but the problem arises from the fact that pressing "Enter" brings the text "up" by one line. In other words, if my textbox contained two lines, only the 2nd one would be visible after pressing the "Enter" key. The textbox would be resized correctly, and the carret positionned at the new line, but the whole content of the textbox won't be visible until the textbox has lost focus.

问题 I have an HTML form with several input boxes and their corresponding enter button. When I type something in the first input box and either press Enter or the button, it works fine.

问题 I have a search input box which when a user presses enter needs to do nothing. I am using EmberJS and Jquery with the below code. Currently it works to disable a pop up from being triggered but for some reason in IE9 when enter is pressed a toggle button becomes in focus. Works fine in Chrome. I've tried tabindex and preventDefault but neither do the trick. if ($el.hasClass('form-control')) { if ( e.which == 13) { this.get('controller').flipit(); } } Thank you.

使用JavaScript在文本框中的Enter键上触发按钮单击

阅读更多关于使用JavaScript在文本框中的Enter键上触发按钮单击

我有一个文本输入和一个按钮（见下文）。当在文本框中按下 Enter 键时，如何使用 JavaScript 触发按钮的click事件？当前页面上已经有一个不同的“提交”按钮，因此我不能简单地将该按钮设为“提交”按钮。而且，如果只从一个文本框中按下该按钮，我只希望按 Enter 键即可单击该特定按钮，没有别的。 <input type="text" id="txtSearch" /> <input type=" button " id="btnSearch" value="Search" onclick ="doSomething();" /> #1楼对于jQuery Mobile，我必须要做 $('#id_of_textbox').live("keyup", function(event) { if(event.keyCode == '13'){ $('#id_of_button').click(); } }); #2楼将按钮设为Submit元素，因此它将是自动的。 <input type = "submit" id = "btnSearch" value = "Search" onclick = "return doSomething();" /> 请注意，您需要一个包含输入字段的 <form> 元素才能完成此工作（感谢Sergey Ilinsky）。
