In the of the web form, we sometimes need to insert the text into the cursor, or replace the text in the selection. At this time, it is powerless to use ordinary .value = "text". The following test code can solve this problem for your reference:</p> <p>Function getActiveText () {obj.currpos = document.selection.createRANGE (). duplicate () // Object Customized Properties Copy of the TextRange object established in the document} Function AddText (STR) {IF Obj.currpos // If the object OBJ exists, the property currposobj.currpos.text = STR // Sets the object OBJ Currently activated the text of the TEXTRANGE object established by the Select area is the value of the parameter STR // Implement the value of the parameter STR in the cursor position Or use the value of the parameter STR to replace the medium text Else Obj.Value = STR // If the object OBJ custom attribute Currpos does not exist / / directly add the value of the parameter STR to the value of the object OBJ} </ script> < Textarea ID = "Obj" οnfοcus = "getActiveText ()" οnchange = "getActiveText ()"> </ textarea> <button onclick = "addText ('Chinese')> addtext </ button> <button onclick =" AddText ( 'English')> AddText </ Button></p></div><div class="text-center mt-3 text-grey"> 转载请注明原文地址:https://www.9cbs.com/read-96542.html</div><div class="plugin d-flex justify-content-center mt-3"></div><hr><div class="row"><div class="col-lg-12 text-muted mt-2"><i class="icon-tags mr-2"></i><span class="badge border border-secondary mr-2"><h2 class="h6 mb-0 small"><a class="text-secondary" href="tag-2.html">9cbs</a></h2></span></div></div></div></div><div class="card card-postlist border-white shadow"><div class="card-body"><div class="card-title"><div class="d-flex justify-content-between"><div><b>New Post</b>(<span class="posts">0</span>) </div><div></div></div></div><ul class="postlist list-unstyled"> </ul></div></div><div class="d-none threadlist"><input type="checkbox" name="modtid" value="96542" checked /></div></div></div></div></div><footer class="text-muted small bg-dark py-4 mt-3" id="footer"><div class="container"><div class="row"><div class="col">CopyRight © 2020 All Rights Reserved </div><div class="col text-right">Processed: <b>0.034</b>, SQL: <b>9</b></div></div></div></footer><script src="./lang/en-us/lang.js?2.2.0"></script><script src="view/js/jquery.min.js?2.2.0"></script><script src="view/js/popper.min.js?2.2.0"></script><script src="view/js/bootstrap.min.js?2.2.0"></script><script src="view/js/xiuno.js?2.2.0"></script><script src="view/js/bootstrap-plugin.js?2.2.0"></script><script src="view/js/async.min.js?2.2.0"></script><script src="view/js/form.js?2.2.0"></script><script> var debug = DEBUG = 0; var url_rewrite_on = 1; var url_path = './'; var forumarr = {"1":"Tech"}; var fid = 1; var uid = 0; var gid = 0; xn.options.water_image_url = 'view/img/water-small.png'; </script><script src="view/js/wellcms.js?2.2.0"></script><a class="scroll-to-top rounded" href="javascript:void(0);"><i class="icon-angle-up"></i></a><a class="scroll-to-bottom rounded" href="javascript:void(0);" style="display: inline;"><i class="icon-angle-down"></i></a></body></html><script> var forum_url = 'list-1.html'; var safe_token = 'sRss_2FzwCfBE68oVW5RyEjT59Gdp6jxM59D4Sm7us01S5dkDGGgLPs_2FgI_2BgFiF6LxG6PCS1aeyGJEPVKcJTVykg_3D_3D'; var body = $('body'); body.on('submit', '#form', function() { var jthis = $(this); var jsubmit = jthis.find('#submit'); jthis.reset(); jsubmit.button('loading'); var postdata = jthis.serializeObject(); $.xpost(jthis.attr('action'), postdata, function(code, message) { if(code == 0) { location.reload(); } else { $.alert(message); jsubmit.button('reset'); } }); return false; }); function resize_image() { var jmessagelist = $('div.message'); var first_width = jmessagelist.width(); jmessagelist.each(function() { var jdiv = $(this); var maxwidth = jdiv.attr('isfirst') ?
