我想通过单击选择文本后出现的按钮来修改所选文本。 在第一次迭代它工作正常 - 根据需要替换文本。 在第二次迭代中,似乎文本是从前一次迭代中保留的(模式未更新)并且没有任何作用。 你能帮忙解决一下吗?演示如下。
我尝试live('click', function ...)
代替click()
来根据这里的一些线程更新模式,但似乎无效。
修改
决定包含整个演示,以便更清晰:
<html>
<head>
<title>Border revision</title>
</head>
<body>
<BR />
<h2>Select text in the red square and then click ? button. First time work, second not. Why? </h2>
<div>
some text <span style="border: solid 2px red" class="VAL">try it</span> some text
second attempt <span style="border: solid 2px red" class="VAL">3</span> doesn't work ;(
<hr><br>
</div>
<hr></br>
<div id="selection-image"></div>
<style type="text/css">
#show-bubb { background:url(bubble.png) 0 0 no-repeat; width:25px; height:29px; position:absolute; top:-50px; left:-50px; }

function getSelected() {
if(window.getSelection) { return window.getSelection(); }
else if(document.getSelection) { return document.getSelection(); }
else {
var selection = document.selection.createRange();
if(selection.text) { return selection.text; }
return false;
}
return false;
}
function processing() {
var selectionImage;
$(document).mouseup(function(e) {
var selection = getSelected();
var parent = selection.anchorNode.parentNode;
if(selection && (selection = new String(selection).replace(/^\s+|\s+$/g,''))) {
if(!selectionImage) {
selectionImage = $('<label>').attr({
//~ href: url,
title: 'Click here to remove border',
//~ target: '_blank',
id: 'show-bubb'
}).hide();
$(document.body).append(selectionImage);
}
selectionImage.css({
top: e.pageY - 30, //offsets
left: e.pageX - 13 //offsets
}).fadeIn();
selectionImage.click(function() {
//parent = selection.anchorNode.parentNode;
if (parent == null) {
//alert(ZOZO);
return "";
}
else {
//create a string selected
var text = document.createTextNode(String(selection));
//~ alert("before");
//alert(String(selection));
parent.parentNode.insertBefore(text, parent.nextSibling);
parent.parentNode.removeChild(parent);
//~ alert("after");
}
});
};
});
$(document.body).mousedown(function() {
if(selectionImage) { selectionImage.fadeOut(); }
});
};
$(document).ready(function() {
processing();
});
</script>
有什么想法吗?

主要问题是您在文档上的每个鼠标上创建新的单击事件。这些点击事件具有不同的父项并按顺序执行。

单击事件,vars通过jquery方法data()
传递给selectionImage$(document).mouseup(function(e) {
var selection = getSelected();
var parent = selection.anchorNode.parentNode;
if(selection && (selection = new String(selection).replace(/^\s+|\s+$/g,''))) {
if(!selectionImage) {
selectionImage = $('<label>').attr({
//~ href: url,
title: 'Click here to remove border',
//~ target: '_blank',
id: 'show-bubb'
}).text('test').click(function() {
var parent = $(this).data('parent');
var selection = $(this).data('selection');
//parent = selection.anchorNode.parentNode;
if (parent == null) {
//alert(ZOZO);
return "";
}
else {
//create a string selected
var text = document.createTextNode(String(selection));
//~ alert("before");
//alert(String(selection));
parent.parentNode.insertBefore(text, parent.nextSibling);
parent.parentNode.removeChild(parent);
//~ alert("after");
}
}).hide();
$(document.body).append(selectionImage);
}
selectionImage.css({
top: e.pageY - 30, //offsets
left: e.pageX - 13 //offsets
}).fadeIn();
selectionImage.data({
selection: selection,
parent: parent
});
};
});
