// This technique is the most likely to be standardized.
// getSelection() returns a Selection object, which we do not document.
return window.getSelection().toString();
}
elseif (document.getSelection) {
// This is an older, simpler technique that returns a string
return document.getSelection();
}
elseif (document.selection) {
// This is the IE-specific technique.
// We do not document the IE selection property or TextRange objects.
return document.selection.createRange().text;
}
}
2、在FireFox下获取input或者textarea中选中的文字，可以用下面的方法：
function getTextFieldSelection(e) {
if (e.selectionStart != undefined && e.selectionEnd != undefined) {
var start = e.selectionStart;
var end = e.selectionEnd;
return e.value.substring(start, end);
}
else
return""; // Not supported on this browser
}
function getTextFieldSelection(e) {
if (e.selectionStart != undefined && e.selectionEnd != undefined) {
var start = e.selectionStart;
var end = e.selectionEnd;
return e.value.substring(start, end);
}
else
return ""; // Not supported on this browser
}
