From: Bruno PrĂ©mont Date: Tue, 10 Feb 2009 20:38:23 +0000 (+0100) Subject: contrib/php-collection: Save/load graph list and fix HTTPS handling. X-Git-Tag: collectd-4.6.0~19^2^2 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=refs%2Fheads%2Fcollectd-4.4;p=collectd.git contrib/php-collection: Save/load graph list and fix HTTPS handling. Hi, An update to the graphing interface. (incremental patch attached) This fixes security complaint by a few browsers when page is accessed via HTTPS and also makes sure the graphs and lists will load if HTTP and HTTPS paths differ. Thanks to Mullet- for spotting this issue. In addition to the fix above this patch adds support for saving current graph list to a cookie and appending graph list read from cookie to the currently displayed list. A future extension would be to allow saving/loading named graph lists so multiple list can coexist (pretty useful when monitoring multiple servers/services) Bruno --- diff --git a/contrib/php-collection/browser.js b/contrib/php-collection/browser.js index 9fcdbabe..6f4d8ec8 100644 --- a/contrib/php-collection/browser.js +++ b/contrib/php-collection/browser.js @@ -37,6 +37,8 @@ function toggleDiv(divID) { } } +var req = null; + // DHTML helper code to asynchronous loading of content function loadXMLDoc(url, query) { if (window.XMLHttpRequest) { @@ -57,12 +59,13 @@ function loadXMLDoc(url, query) { } // DHTML new-content dispatcher -function processReqChange() { +function processReqChange(evt) { if (req.readyState == 4) { if (req.status == 200) { - response = req.responseXML.documentElement; - method = response.getElementsByTagName('method')[0].firstChild.data; - result = response.getElementsByTagName('result')[0]; + var response = req.responseXML.documentElement; + var method = response.getElementsByTagName('method')[0].firstChild.data; + var result = response.getElementsByTagName('result')[0]; + req = null; eval(method + '(result)'); } } @@ -265,9 +268,9 @@ function RefreshButtons() { } var nextGraphId = 1; +var graphList = new Array(); function GraphAppend() { - var graphs = document.getElementById('graphs'); var host_list = document.getElementById('host_list'); var host = host_list.selectedIndex >= 0 ? host_list.options[host_list.selectedIndex].value : '/'; var plugin_list = document.getElementById('plugin_list'); @@ -278,6 +281,15 @@ function GraphAppend() { var type = type_list.selectedIndex >= 0 ? type_list.options[type_list.selectedIndex].value : '/'; var tinst_list = document.getElementById('tinst_list'); var tinst = tinst_list.selectedIndex >= 0 ? tinst_list.options[tinst_list.selectedIndex].value : '/'; + var time_list = document.getElementById('timespan'); + var timespan = time_list.selectedIndex >= 0 ? time_list.options[time_list.selectedIndex].value : ''; + var tinyLegend = document.getElementById('tinylegend').checked; + var logarithmic = document.getElementById('logarithmic').checked + GraphDoAppend(host, plugin, pinst, type, tinst, timespan, tinyLegend, logarithmic); +} + +function GraphDoAppend(host, plugin, pinst, type, tinst, timespan, tinyLegend, logarithmic) { + var graphs = document.getElementById('graphs'); if (host != '/' && plugin != '/' && pinst != '/' && type != '/') { var graph_id = 'graph_'+nextGraphId++; @@ -292,14 +304,15 @@ function GraphAppend() { graph_title = type+(tinst.length > 0 ?
