Martin Grigorov commented on WICKET-5132: ----------------------------------------- The improvement is applied. Please test with 6.8.0-SNAPSHOT/7.0.0-SNAPSHOT if you can. https://git-wip-us.apache.org/repos/asf/wicket/repo?p=wicket.git;a=commitdiff;h=62562dc4581046ad268c11a66f0dc71d92ddf456 > Evaluation of returned data (which includes alot of javascript) very slow > after ajax call in IE10. > -------------------------------------------------------------------------------------------------- > > Key: WICKET-5132 > URL: https://issues.apache.org/jira/browse/WICKET-5132 > Project: Wicket > Issue Type: Bug > Components: wicket > Affects Versions: 6.0.0 > Environment: IE10 > Reporter: Bas Veenema > Assignee: Martin Grigorov > Labels: javascript, performance > Fix For: 6.7.0 > > Attachments: response_script.txt > > Original Estimate: 2h > Remaining Estimate: 2h > > We're using ajax to update a treetable. In IE10, when the ajax call returns > the data, which contains alot of javascript code, processEvaluation in > wicket-ajax-jquery.js stalls on var text = jQuery(node).text(); > In jQuery procedure Sizzle.getText is called, which eventually returns > property elem.textContent. In IE10 this last statement takes about 26 seconds > for our case while the same statement in chrome takes about 6 ms. > It seems strange that IE10 takes this long to return the textContent of a > node, but why is this necessary in the first place? > The purpose of var text = jQuery(node).text() would be to get the text of the > node. I think it would suffice to state var text = > node.childNodes[0].nodeValue instead of var text = Query(node).text(), > because the text is in the node itself, and it's not necessary to get the > text from its descendants, because it has no descendants. > In our case this modification improves the duration from 25915 ms to 8 ms in > IE10. -- This message is automatically generated by JIRA.
