避免使用JavaScript或jQuery重复结果(avoid repeating of result using JavaScript or jQuery)
大家好，我一直在想如何避免使用for循环在JavaScript或jQuery上显示相同的结果
这是我的代码：
function displayData(e) { var html = ''; var html2 = ''; var x = ''; var mapDiv = document.getElementById('mapContainer'), i = 0, dataIndex, tooltipDiv, key mapMarkers = $(mapDiv).find('.e-mapMarker'), index = 0; var divCont = $(mapDiv).find('#rightdiv'), index = 0; for (i = 0; i < mapMarkers.length; i++) { if (e.target.parentNode.parentNode == mapMarkers[i]) { index = i; } } html += '<div id="infocontainer">'; html += '<div class="p-image"><img src="src/images/retrofit.png"/></div>'; html += '<div class="popupdetail">'; html += '<div class="p-name"> Site Name: ' + flsSites[index].site_name + '</div>'; html += '<div class="p-name"> Site Status: ' + flsSites[index].status + '</div>'; html += '<div class="p-name"> Country: ' + flsSites[index].country_name + '</div>'; html += '</div>'; html += '</div>'; html2 += '<div class="rightcontainer">'; html2 += '<img id="productimage" src="src/images/retrofit.png" onclick="DisplayProfileCard();"/>'; html2 += '<div id="imagedetail">'; html2 + '<input type="hidden" value='+ flsSites[index].serial_number +'/>'; html2 += '<span class="details">Product Type:' + flsSites[index].serial_number +'</span>'; html2 += '<span class="details">Version / Size <img class="row_one_icon lightbulb_icon" id="lightbulb" src="src/images/lightbulb1.png" onClick="LightBulb()" /><img id="convert" class="row_one_icon arrow_icon" src="src/images/arrow_Off.png" onClick="Conversion()"/><img id="lightning" class="row_one_icon" src="src/images/lightningOff.png" onClick="Lightning()"/><img id="bullseye" class="row_one_icon bullseye" src="src/images/bullseye_off.png" onClick="BullsEye()"/></span>'; html2 += '<span class="details">Estimated annual Spend <img class="row_one_icon ribbon" src="src/images/ribbon1.png"/><img class="row_one_icon map" src="src/images/map1.png"/><img class="row_one_icon paper_stack" id="paper" src="src/images/paper_stack_Off.png" onclick="PaperStack()"/><img class="row_one_icon chain" id="chain" src="src/images/chain_Off.png" onClick="ChainLink()"/></span>'; html2 += '<span class="details">Site name / manufacturer</span>'; html2 += '<span class="details">Selling Sales Eng</span>'; html2 += '</div>' html2 += '</div>'; if (!document.getElementById('map_tooltip')) { tooltipdiv = $("<div></div>").attr('id', "map_tooltip"); $(document.body).append(tooltipdiv); $(tooltipdiv).css({ "display": "none", "padding": "5px", "position": "absolute", "z-index": "13000", "cursor": "default", "font-family": "Segoe UI", "color": "#707070", "font-size": "12px", "pointer-events": "none", "background-color": "#FFFFFF", "border": "1px solid #707070" }); } else { tooltipdiv = $("#map_tooltip"); $(tooltipdiv).css({ "left": (e.pageX + 5), "top": (e.pageY + 5) }); $(tooltipdiv).html(html).show("slow"); //$('#defaulttext').hide(); //$('#searchcontainer').append(html2); //$('.rightcontainer').eq($(this).index()).addClass('background'); $(html2).appendTo("#searchcontainer"); }现在在这段代码中，我能够通过将鼠标悬停在地图上的标记上来显示我的结果，但是如果我返回我之前悬停的标记而不是突出显示其相应的结果，它将在下面进行另一个相同结果的渲染我不需要
Hi guys I have been wondering how can I avoid displaying of the same result on JavaScript or jQuery using for loop
Here is my code:
function displayData(e) { var html = ''; var html2 = ''; var x = ''; var mapDiv = document.getElementById('mapContainer'), i = 0, dataIndex, tooltipDiv, key mapMarkers = $(mapDiv).find('.e-mapMarker'), index = 0; var divCont = $(mapDiv).find('#rightdiv'), index = 0; for (i = 0; i < mapMarkers.length; i++) { if (e.target.parentNode.parentNode == mapMarkers[i]) { index = i; } } html += '<div id="infocontainer">'; html += '<div class="p-image"><img src="src/images/retrofit.png"/></div>'; html += '<div class="popupdetail">'; html += '<div class="p-name"> Site Name: ' + flsSites[index].site_name + '</div>'; html += '<div class="p-name"> Site Status: ' + flsSites[index].status + '</div>'; html += '<div class="p-name"> Country: ' + flsSites[index].country_name + '</div>'; html += '</div>'; html += '</div>'; html2 += '<div class="rightcontainer">'; html2 += '<img id="productimage" src="src/images/retrofit.png" onclick="DisplayProfileCard();"/>'; html2 += '<div id="imagedetail">'; html2 + '<input type="hidden" value='+ flsSites[index].serial_number +'/>'; html2 += '<span class="details">Product Type:' + flsSites[index].serial_number +'</span>'; html2 += '<span class="details">Version / Size <img class="row_one_icon lightbulb_icon" id="lightbulb" src="src/images/lightbulb1.png" onClick="LightBulb()" /><img id="convert" class="row_one_icon arrow_icon" src="src/images/arrow_Off.png" onClick="Conversion()"/><img id="lightning" class="row_one_icon" src="src/images/lightningOff.png" onClick="Lightning()"/><img id="bullseye" class="row_one_icon bullseye" src="src/images/bullseye_off.png" onClick="BullsEye()"/></span>'; html2 += '<span class="details">Estimated annual Spend <img class="row_one_icon ribbon" src="src/images/ribbon1.png"/><img class="row_one_icon map" src="src/images/map1.png"/><img class="row_one_icon paper_stack" id="paper" src="src/images/paper_stack_Off.png" onclick="PaperStack()"/><img class="row_one_icon chain" id="chain" src="src/images/chain_Off.png" onClick="ChainLink()"/></span>'; html2 += '<span class="details">Site name / manufacturer</span>'; html2 += '<span class="details">Selling Sales Eng</span>'; html2 += '</div>' html2 += '</div>'; if (!document.getElementById('map_tooltip')) { tooltipdiv = $("<div></div>").attr('id', "map_tooltip"); $(document.body).append(tooltipdiv); $(tooltipdiv).css({ "display": "none", "padding": "5px", "position": "absolute", "z-index": "13000", "cursor": "default", "font-family": "Segoe UI", "color": "#707070", "font-size": "12px", "pointer-events": "none", "background-color": "#FFFFFF", "border": "1px solid #707070" }); } else { tooltipdiv = $("#map_tooltip"); $(tooltipdiv).css({ "left": (e.pageX + 5), "top": (e.pageY + 5) }); $(tooltipdiv).html(html).show("slow"); //$('#defaulttext').hide(); //$('#searchcontainer').append(html2); //$('.rightcontainer').eq($(this).index()).addClass('background'); $(html2).appendTo("#searchcontainer"); }Now in this code I was able to display my result on a div by hovering on a marker on the map but if I return on my previous hovered marker instead of highlighting its corresponding result, it will just make another rendering of the same result below in which I dont need

你可以试试
entries <- unlist(strsplit(text, "\\n")) #separate entries by line breaks entries <- entries[nchar(entries) > 0] #remove empty lines as.data.frame(matrix(entries, ncol=3, byrow=TRUE)) #assemble dataframe # V1 V2 V3 #1 DOB Name Address #2 13-03-2003 ABC xyz. #3 12-08-2004 dfs 1 infinite loop.数据
text <-'DOB Name Address 13-03-2003 ABC xyz. 12-08-2004 dfs 1 infinite loop.' df <- read.table(text = text)You could try
entries <- unlist(strsplit(text, "\\n")) #separate entries by line breaks entries <- entries[nchar(entries) > 0] #remove empty lines as.data.frame(matrix(entries, ncol=3, byrow=TRUE)) #assemble dataframe # V1 V2 V3 #1 DOB Name Address #2 13-03-2003 ABC xyz. #3 12-08-2004 dfs 1 infinite loop.data
text <-'DOB Name Address 13-03-2003 ABC xyz. 12-08-2004 dfs 1 infinite loop.' df <- read.table(text = text)

sink()有自己的append参数。 正如Gregor所提到的，在cat() append仅在使用file有效。 但是，如果将所有cat()调用放在sink()调用之间，则根本不需要使用append ，因为sink()将继续附加到文件，直到调用sink(NULL) 但是对于你的情况，我认为你想为你的sink()块做这样的事情： sink("output.txt", type=c("output", "message"), append = TRUE) cat("Hello", "\n") cat("Wor ... -
