如何在光标所在位置插入一些文本?
我正在升级一些可以在 IE 上运行的 Javascript。但是,我遇到了一些问题。
这是 IE 代码:
var range = document.getElementById('text').contentWindow.window
.document.getElementById('Content').createTextRange();
var textObj = document.getElementById('text').contentWindow.window
.document.getElementById('Content');
var textFieldValue = theSmile;
if (range && textObj.CursorPos) {
var CursorPos = textObj.CursorPos;
CursorPos.text = CursorPos.text.charAt(CursorPos.text.length - 1)
== ' ' ?' ' + textFieldValue : textFieldValue;
} else {
textObj.value = textFieldValue;
}
对于非 IE 浏览器,我尝试将 CreateTextRange
替换为 CreateRange
,但这没有帮助。使用这样的代码:
var range;
var textObj;
var iframeEl = document.getElementById('text');
if (iframeEl.contentDocument) { // DOM
range = iframeEl.contentDocument.getElementById('Content').createRange;
textObj= iframeEl.contentDocument.getElementById('Content');
} else if (iframeEl.contentWindow) { // IE win
range = iframeEl.contentWindow.document.getElementById('Content')
.createTextRange;
textObj= iframeEl.contentWindow.document.getElementById('Content');
}
I'm upgrading some Javascript which works on IE. However, I'm having some problems.
Heres the IE code:
var range = document.getElementById('text').contentWindow.window
.document.getElementById('Content').createTextRange();
var textObj = document.getElementById('text').contentWindow.window
.document.getElementById('Content');
var textFieldValue = theSmile;
if (range && textObj.CursorPos) {
var CursorPos = textObj.CursorPos;
CursorPos.text = CursorPos.text.charAt(CursorPos.text.length - 1)
== ' ' ?' ' + textFieldValue : textFieldValue;
} else {
textObj.value = textFieldValue;
}
I've tried replacing CreateTextRange
with CreateRange
for non-IE browsers, but this doesn't help. With code like this:
var range;
var textObj;
var iframeEl = document.getElementById('text');
if (iframeEl.contentDocument) { // DOM
range = iframeEl.contentDocument.getElementById('Content').createRange;
textObj= iframeEl.contentDocument.getElementById('Content');
} else if (iframeEl.contentWindow) { // IE win
range = iframeEl.contentWindow.document.getElementById('Content')
.createTextRange;
textObj= iframeEl.contentWindow.document.getElementById('Content');
}
