Question

如何在iframe中找到并选择“String”，然后用另一个字符串替换？，

以下代码运作正常，但我无法将它们组合在一起，

function Find(txt) {
        var iframe = document.getElementById("Text_ifr");
        var iframe_contents = iframe.contentDocument.body.innerHTML;
        if (iframe_contents.indexOf(txt) >= 0) {
            alert('Found')
        }
        else { alert('Not Found') }
        return false;
    }

function replaceSelectedText(replacementText) {
        var iframe = document.getElementById("Text_ifr");
        var win = iframe.contentWindow;
        var doc = iframe.contentDocument || win.document;
        var sel, range;
        if (win.getSelection) {
            sel = win.getSelection();
            if (sel.rangeCount) {
                range = sel.getRangeAt(0);
                range.deleteContents();
                range.insertNode(doc.createTextNode(replacementText));
            }
        } else if (doc.selection && doc.selection.createRange) {
            range = doc.selection.createRange();
            range.text = replacementText;
        }
    }

由于
