我有Web应用程序,用户可以在其中键入iframe(富文本编辑器),当他们单击一个按钮时,iframe将显示。当用户单击新iframe按钮时的HTML代码: <input name="add_button" type="button" value="New frame" onClick="javascript:add_new_frame();"/>
用于创建 iframe 和 DesignMode 的 JavaScript 代码
function add_new_frame(){
$("<iframe class="a" id="a" name="a"/>").appendTo(id);
var editor = document.getElementById ("a");
editorDoc = editor.contentWindow.document;
editorDoc1 = document.getElementById ("a").contentDocument;
var editorBody = editorDoc.body;
if ('spellcheck' in editorBody) { // Firefox
editorBody.spellcheck = false;
}
if ('contentEditable' in editorBody) {
// allow contentEditable
editorBody.contentEditable = true;
editorDoc1.designMode = "on";
}
else {
if ('designMode' in editorDoc1) {
editorDoc1.designMode = "on";
}
}
}
我已经在上面测试过(铬,歌剧,野生动物园,IE),它工作正常。但是,它在 FF 上不起作用,iframe 显示出来,但我无法编辑它(设计模式不起作用)。有什么解决办法吗?对不起,英语不好
你在 iframe 元素中错过了 \ 来屏蔽"
function add_new_frame(){
$("<iframe class="a" id="a" name="a"/>").appendTo(id);
var editor = document.getElementById ("a");
editorDoc = editor.contentWindow.document;
editorDoc1 = document.getElementById ("a").contentDocument;
var editorBody = editorDoc.body;
if ('spellcheck' in editorBody) { // Firefox
editorBody.spellcheck = false;
}
if ('contentEditable' in editorBody) {
// allow contentEditable
editorBody.contentEditable = true;
editorDoc1.designMode = "on";
}
else {
if ('designMode' in editorDoc1) {
editorDoc1.designMode = "on";
}
}
}
