对于标准textareas,我使用此
plugin创建占位符.我怎样才能扩展tinymce以便这也能以这种方式工作.
例如,从textarea属性读取默认值,然后在用户关注iframe时清除.
与CKEditor类似：http://alfonsoml.blogspot.com.es/2012/04/placeholder-text-in-ckeditor.html
解决方法
如果没有占位符属性,我收到错误.
我结合了这个答案的代码：
jQuery hasAttr checking to see if there is an attribute on an element获取下面修改的代码处理该场景：
setup: function(ed) {
// Set placeholder
var tinymce_placeholder = $('#'+ed.id);
var attr = tinymce_placeholder.attr('placeholder');
// For some browsers,`attr` is undefined; for others,// `attr` is false. Check for both.
if (typeof attr !== 'undefined' && attr !== false) {
var is_default = false;
ed.onInit.add(function(ed) {
// get the current content
var cont = ed.getContent();
// If its empty and we have a placeholder set the value
if(cont.length == 0){
ed.setContent(tinymce_placeholder.attr("placeholder"));
// Get updated content
cont = tinymce_placeholder.attr("placeholder");
}
// convert to plain text and compare strings
is_default = (cont == tinymce_placeholder.attr("placeholder"));
// nothing to do
if (!is_default){
return;
}
});
ed.onMouseDown.add(function(ed,e) {
// replace the default content on focus if the same as original placeholder
if (is_default){
ed.setContent('');
}
});
}
}
