我正在使用Kendo UI编辑器的MVC扩展。是否可以选择设置除HTML内容之外的最小和最大字符数。
我使用了StringLength属性,但包含HTML内容。
答案 0 :(得分:1)
你对剑道编辑没有这些选择是正确的。使用一些JavaScript和jQuery可以做到这一点。这个例子使用的是Kendo Core(像ASP.NET MVC这样的Kendo Wrappers仍然可以在ASP.NET MVC中工作,你不会在JavaScript中调用$("#editor")。kendoEditor())。
这是我的jsFiddle example。

<p>Kendo UI Editor allows your users to edit HTML in a familiar, user-friendly way.
<br />In this version, the Editor provides the core HTML editing engine, which includes basic text formatting, hyperlinks, lists, and image handling. The widget <strong>outputs identical HTML</strong> across all major browsers, follows accessibility standards and provides API for content manipulation.</p>
<p>Features include:</p>
<ul>
<li>Text formatting & alignment</li>
<li>Bulleted and numbered lists</li>
<li>Hyperlink and image dialogs</li>
<li>Cross-browser support</li>
<li>Identical HTML output across browsers</li>
<li>Gracefully degrades to a <code>textarea</code> when JavaScript is turned off</li>
</ul>
</textarea>
</div>

$(function () {

var minChar = 100;
var maxChar = 600;
var iframe = $("iframe");
// Change event for iframe body content
iframe.contents().find("body").on('keydown', function (e) {
//Clean up
$("#textCount").removeClass("warning");
// Get Body (.text() strips out HTML tags)
var data = $(this).text();
if (this.which < 32) {
return; // Do nothing
}
var isEditKey = (e.keyCode == 8 || e.keyCode == 46);
if (data.length == maxChar && !isEditKey) {
e.preventDefault();
} else if (data.length > maxChar) {
// Maximum exceeded
$(this).text(data.substring(0, maxChar));
} else if (data.length < minChar) {
$("#textCount").addClass("warning");
}
$("#textCount").text(data.length);
});
// OnLoad call to get starting count
var data = iframe.contents().find("body").text();
$("#textCount").text(data.length);
});
