Convert lowercase letter to upper case in javascript
提问by priyanka.bangalore
I have a codethat will convert lower case letters to uppercase but it works only with IE and not in Crome or Firefox.
我有一个代码可以将小写字母转换为大写字母，但它仅适用于 IE 而不适用于 Crome 或 Firefox。
function ChangeToUpper()
{
key = window.event.which || window.event.keyCode;
if ((key > 0x60) && (key < 0x7B))
window.event.keyCode = key-0x20;
}
<asp:TextBox ID="txtJobId" runat="server" MaxLength="10" onKeypress="ChangeToUpper();"></asp:TextBox>
Even I tried with
即使我试过
document.getElementById("txtJobId").value=document.getElementById("txtJobId").value.toUpperCase();
onBlur event of the textbox
文本框的 onBlur 事件
What should I do to make it work in all browsers?
我应该怎么做才能使它在所有浏览器中都能正常工作？
Thanks

<script type="text/javascript">
function ChangeCase(elem)
{
elem.value = elem.value.toUpperCase();
}
</script>
<input onblur="ChangeCase(this);" type="text" id="txt1" />
separate javascript from your HTML
将 javascript 与 HTML 分开
window.onload = function(){
var textBx = document.getElementById ( "txt1" );
textBx.onblur = function() {
this.value = this.value.toUpperCase();
};
};
<asp:TextBox ID="txt1" runat="server"></asp:TextBox>
If the textbox is inside a naming container then use something like this
如果文本框在命名容器内，则使用类似这样的内容
var textBx = document.getElementById ("<%= txt1.ClientID %>");
textBx.onblur = function() {
this.value = this.value.toUpperCase();
};)

You can simply use CSS and do text-transform:uppercaseand on submit you run toUppercase(). Or you just submit as mixed and you capitalize letters on server side :)
您可以简单地使用 CSS 并text-transform:uppercase在提交时运行toUppercase()。或者你只是混合提交，然后在服务器端将字母大写:)

If you don't want to make an explicit JavaScript function, here you can do it in just one line:
如果你不想创建一个显式的 JavaScript 函数，你可以在这里只用一行来完成：
Convert to lower and upper case respectively:
分别转换为小写和大写：
<asp:TextBox ID="txt1" onblur='this.value = this.value.toLowerCase();'></asp:TextBox>
<asp:TextBox ID="txt1" onblur='this.value = this.value.toUpperCase();'></asp:TextBox>
