任务是大写字符串的第一个字母而不使用toUpperCase()方法借助jQuery。下面讨论了两种方法：
方法1：在此示例中, css()方法用于设置文字转换属性重视大写.
例子：
<!DOCTYPE HTML>
< html >
< head >
< title >

string to upper case using jQuery?
</ title >
< script src =
"https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js" >
</ script >
</ head >
< body style = "text-align:center;" >
< h1 style = "color:green;" >
lsbin
</ h1 >
< p >
Click on the button to
perform the operation.
</ p >
Type Here: < input id = "input" />
< br >< br >
< button onclick = "GFG_Fun()" >
Click Here
</ button >
< p id = "GFG" ></ p >
< script >
var geeks = document.getElementById('GFG');
function GFG_Fun() {
$('#input').css('textTransform', 'capitalize');
geeks.innerHTML = "Text is capitalized";
}
</ script >
</ body >
</ html >输出如下：
方法二：在此示例中, 我们使用CSS属性执行操作。新的ID已添加到设置属性的元素中文字转换to大写.
例子：
<!DOCTYPE HTML>
< html >
< head >
< title >

< script src =
"https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js" >
</ script >
< style >
#capital {
text-transform: capitalize;
}
</ style >
</ head >
< body style = "text-align:center;" >
< h1 style = "color:green;" >
lsbin
</ h1 >
< p >
Click on the button to
perform the operation.
</ p >
Type Here: < input id = "input" />
< br >< br >
< button onclick = "GFG_Fun()" >
Click Here
</ button >
< p id = "GFG" ></ p >
< script >
var geeks = document.getElementById('GFG');
function GFG_Fun() {
$('#input').attr('id', 'capital');
geeks.innerHTML = "Text is capitalized";
}
</ script >
</ body >
</ html >输出如下：
