如何选择焦点上的textarea中的所有文本(在safari中) [英] how to select all text in textarea on focus (in safari)
问题描述
请访问一个实际的例子,我们可以看到一个textarea文件的内容。这里: http://jsfiddle.net/mikkelbreum/aSvst/1
使用jQuery,这是我的代码。 (IN SAFARI)它使得在点击事件的情况下选择文本,而不是焦点事件:
$('textarea .automarkup')
.mouseup(function(e){
//修正safari / chrome问题
e.preventDefault();
})
.focus(函数(e){
$(this).select();
})
.click(function(e){
$(this).select();
});
最简单的做法是将现有的代码有一个计时器,因为焦点
事件在WebKit中一般来说太早了:
jsFiddle例子:http://jsfiddle.net/NWaav/2/
代码: p>
$('textarea.automarkup')。焦点(函数(){
var $ this = $(this); ();
$ this.select();
window.setTimeout(function(){
$ this.select();
},1) ;
//解决WebKit的小问题
函数mouseUpHandler(){
//防止进一步的mouseup干预
$ this.off(mouseup,mouseUpHandler) ;
return false;
}
$ this.mouseup(mouseUpHandler);
});
I can't work out why I can't get the the content of a textarea to be selected when the textarea receives focus.

Using jQuery, this is my code. (IN SAFARI) It makes the text selected in case of the click event, but not the focus event:
$('textarea.automarkup')
.mouseup(function(e){
// fixes safari/chrome problem
e.preventDefault();
})
.focus(function(e){
$(this).select();
})
.click(function(e){
$(this).select();
});
The simplest thing to do is to combine your existing code with a timer, since the focus
event is generally too early in WebKit:
jsFiddle example: http://jsfiddle.net/NWaav/2/
Code:
$('textarea.automarkup').focus(function() {
var $this = $(this);
$this.select();
window.setTimeout(function() {
$this.select();
}, 1);
// Work around WebKit's little problem
function mouseUpHandler() {
// Prevent further mouseup intervention
$this.off("mouseup", mouseUpHandler);
return false;
}
$this.mouseup(mouseUpHandler);
});
