我正在升級一些適用於IE的Javascript。但是,我遇到了一些問題。如何在光標所在處插入一些文字?
繼承人的IE代碼:
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;
}
我試着CreateRange
更換CreateTextRange
對非IE瀏覽器,但是這並沒有幫助。用這樣的代碼:
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');
}
