表情符号点击textarea [英] smilies to textarea on click
问题描述
我有一个小问题
我想单击我的笑脸并将文本插入到textarea。
,当我想在稍后添加笑脸时,笑脸应该被添加到光标位置,而不是在textarea的末尾。
这是我的 html 代码:
< textarea id =descriptionname =description><<< ; / textarea的>
< div id =emoticons>
< a href =#title =:)>< img alt =:)border =0src =/ images / emoticon-happy.png/>< ; / A>
< a href =#title =:(>< img alt =:(border =0src =/ images / emoticon-unhappy.png/>< ; / a>
< a href =#title =:o>< img alt =:oborder =0src =/ images / emoticon- surprised.png />< / a>
< / div>
strong> JS 代码:
$('#emoticons a')。click(function(){$ b $($#
)var smiley = $(this).attr('title');
$('#description')。val($('#description')。val()++ smiley +);
});
在这里您可以看到结果(NO WRAP - BODY)

我为我的javascript代码使用了一个extern JS文件...
您是否知道为什么代码不在NO WRAP中运行 - HEAD模式?

感谢您的帮助
问候语
另外,您可以使用以下功能:
函数ins2pos(str,id){
var TextArea = document.getElementById(id);
var val = TextArea.value;
var before = val.substring(0,TextArea.selectionStart);
var after = val.substring(TextArea.selectionEnd,val.length);
TextArea.value = before + str + after;
}
对于您的示例,请查看 here 。
UPD 1:
function setCursor(elem,pos){
if(elem.setSelectionRange){
elem.focus();
elem.setSelectionRange(pos,pos);
} else if(elem.createTextRange){
var range = elem.createTextRange();
range.collapse(true);
range.moveEnd('character',pos);
range.moveStart('character',pos);
range.select();
我更新了jsFiddle上的代码,因此,查看新的例如,看此处。
I have a little question
I want to click on my smileys and insert the text to the textarea. and when I want to add a smiley later, the smiley should be added to the cursor position and not at the end in the textarea.
This is my html code:
<textarea id="description" name="description"></textarea>
<div id="emoticons">
<a href="#" title=":)"><img alt=":)" border="0" src="/images/emoticon-happy.png" /></a>
<a href="#" title=":("><img alt=":(" border="0" src="/images/emoticon-unhappy.png" /></a>
<a href="#" title=":o"><img alt=":o" border="0" src="/images/emoticon-surprised.png" /></a>
</div>
This is my JS code:
$('#emoticons a').click(function(){
var smiley = $(this).attr('title');
$('#description').val($('#description').val()+" "+smiley+" ");
});
Here you can see the result (NO WRAP - BODY) http://jsfiddle.net/JVDES/8/
I use an extern JS file for my javascript-code...
Do you know why the code isn't running in NO WRAP - HEAD mode?

Thanks for helping

Also, you can use something this function:
function ins2pos(str, id) {
var TextArea = document.getElementById(id);
var val = TextArea.value;
var before = val.substring(0, TextArea.selectionStart);
var after = val.substring(TextArea.selectionEnd, val.length);
TextArea.value = before + str + after;
}
For your example, look here.
UPD 1:
To set cursor at specified position, use the next function:
function setCursor(elem, pos) {
if (elem.setSelectionRange) {
elem.focus();
elem.setSelectionRange(pos, pos);
} else if (elem.createTextRange) {
var range = elem.createTextRange();
range.collapse(true);
range.moveEnd('character', pos);
range.moveStart('character', pos);
range.select();
}
}
I updated code on jsFiddle, so, to view new example, look here.
