问题 I'm using this function in order to replace <DIV>New Divs</DIV> with <BR> in break lines on contentEditable divs using Safari and Chrome: $("#form_description").live("keypress", function(e){ if (e.which == 13) { if (window.getSelection) { var selection = window.getSelection(), range = selection.getRangeAt(0), br = document.createElement("br"); range.deleteContents(); range.insertNode(br); range.setStartAfter(br); range.setEndAfter(br); range.collapse(false); selection.removeAllRanges();

问题 I have a contenteditable div and want to get the user's selection when they click a span . My problem is that when I click the span , the selection gets unselected so window.getSelection().toString() returns '' . How can I get this to work on click of a span ? I know the actual getSelection() works, because if I wrap window.getSelection().toString() in a setTimeout of 5 seconds, after 5 seconds, I get the selected text! My code: $('#btn').click(function() { console.log(window.getSelection()

问题 Its a followup question of this. I'm trying to wrap the selected text in a div using window.getSelection() but its not working in iPad because window.getSelection().rangeCount is 0. Demo: http://jsfiddle.net/codef0rmer/jE4w5/ Is there any workaround for this to work in iPad? 回答1: You can use rangy for text selection and highlighting. jQuery Mobile along with backbone.js breaks the page so I used jQuery FastClick plugin 来源： https://stackoverflow.com/questions/11465253/how-to-wrap-selected-text

问题 When I use: chart.getChart().getSelection()[0] on a chart (from a chartwrapper, hence the getChart() first), the getSelection() function returns only a row-property but no column property even though my 'chart' is a table and clicking anywhere within it should return both a row and column property. Is this a known google charts bug? Does anyone know of a workaround? Also I have found this topic on google groups: https://groups.google.com/forum/#!topic/google-visualization-api/O_t7-s96A9w here
