Question

使用ASP.NET MVC，我有一个包含TextAreaFor的View，我希望用户能够输入一些注释并即时保存它们，请参阅之前保存的注释（无论是否由它们保存）或其他一些用户），以及修改现有笔记（比如添加其他笔记）。这就是我拥有的......

视图中的div：

    <div class="form-group">
        <label for="InternalNotes" class="control-label">Internal Notes</label>
        @Html.TextAreaFor(w => w.InternalNotes, new { @class = "form-control" , @id="notes" })  @*this is editable*@
    </div>
    <div class="form-group">
        <div class="col-xs-6">
            <button type="button" id="savenotes" class="btn btn-default btn-primary"><span class="glyphicon glyphicon-floppy-disk"></span> Save Request Notes</button>
            <div style="color:green; display:none" id="notessuccess">Notes successfully saved</div>
            <div style="color:red; display:none" id="noteserror">Notes unable to be saved</div>
        </div>
        <div class="col-xs-6 text-right">
            <button type="submit" id="deletereq" class="btn btn-default btn-primary" value="delete" name="submit"><span class="glyphicon glyphicon-remove"></span> Delete Request</button>
        </div>
    </div>

因此，用户可以在TextAreaFor中键入内容，然后点击＆＃34; savenotes＆＃34;按钮，应该通过Ajax保存它们。这是jQuery：

$(document).ready(function () {

    $("#savenotes").click(function () {

        $("#notessuccess").hide();
        $("#noteserror").hide();

        var id = @Model.AccessRequestId;
        var notes = document.getElementById("notes").textContent;  //innerText;

        $.ajax({
            data: { 'id': id, 'notes': notes },
            type: 'POST',
            //contentType: "application/json; charset=utf-8",
            url: '/Administration/SaveRequestNotes',
            success: function (data) {
                if (data.success == "ok") {
                    $("#notessuccess").fadeIn();
                } else {
                    $("#noteserror").fadeIn();
                }
            },
            fail: function (data) {
                $("#noteserror").fadeIn();
            }
        });
    });
});

＆＃34; innerText＆＃34;被注释掉了，因为这是我最初使用的，但它只在Internet Explorer中工作 - 另一个用户正在使用Chrome，在那里他可以看到已经存在的其他用户注释，但当他和＃39; d除了他们之外还试着保存笔记，它会把它全部吹掉所以笔记会是空的！

所以我将其改为＆＃34; textContent＆＃34;。这仍然适用于Internet Explorer，但现在在Chrome和Firefox中，虽然它不会清空现有笔记，但仍然无法保存添加的新笔记。什么是与浏览器无关的方式，我可以使这项工作，以便每个人的笔记将得到适当保存，无论他们使用什么？

谢谢！

您可以使用jQuery print('What is the term to be searched?') term = input() browser = webdriver.Firefox(executable_path ='/usr/local/bin/geckodriver') browser.get('https://google.com/search?q=' + term) try: link = browser.find_element_by_link_text("Hello") # (I want to make it so the first page has no links of interest, so I can proceed to clicking the next page) except NoSuchElementException: nextPage = browser.find_element_by_css_selector('Css of next page button) nextPage.click()方法获取文本用户输入到textarea

您可能还会考虑使用Url.Action帮助程序方法生成操作方法的正确相对路径。
