标签: jquery css struts2 scroll displaytag

我使用displaytag创建了一个表。我想固定表头或列标题,只应滚动表的主体。我能够使包含表的div可滚动。但滚动表格的标题时也会滚动。它没有保持固定。我尝试了一些方法。但我没有运气。可以有人帮我这个吗? 提前谢谢。

我的代码:

<div id="ratesTableDiv" style="overflow-y: auto;height:250px;" >
                <display:table class="tablesorter" export="false" id="data" class="displayTableBorder"
                    summary="This is the only table in the rates tab. It has the rates data for the selected plan." style="width:700px;" 
                    name="PlanSummaryDTO.planRateList" uid="rates" rules="rows"
                    requestURI="PlanSummary"
                    decorator="com.cgi.hix.web.decorators.PortalHomePlansDecorator">
                    <display:setProperty name="paging.banner.placement" value="bottom" />
                    <display:setProperty name="basic.empty.showtable" value="true" />
                    <display:setProperty name="paging.banner.onepage" value="" />
                    <display:setProperty name="paging.banner.no_items_found" value="" />
                    <display:setProperty name="paging.banner.one_item_found" value="" />
                    <display:setProperty name="paging.banner.all_items_found" value="" />
                    <display:setProperty name="paging.banner.some_items_found" value="" />
                    <display:setProperty name="paging.banner.group_size" value="5" />
                    <display:setProperty name="paging.banner.full"
                        value='<p><span id="hix-pagination"><span> <a id="doublePrevRates" class="prev" href="{1}">&#9668;&#9668;</a> <a id="singlePrevRates" class="prev" href="{2}">&#9668;</a> {0} <a id="singleNextRates" class="next" href="{3}">&#9658;</a> <a id="doubleNextRates" class="next" href="{4}">&#9658;&#9658; </a></span></span></p>' />
                    <display:setProperty name="paging.banner.first"
                        value='<p><span id="hix-pagination"><span> <a id="doublePrevRates" class="prev" href="{1}">&#9668;&#9668;</a> <a id="singlePrevRates" class="prev" href="{2}">&#9668;</a> {0} <a id="singleNextRates" class="next" href="{3}">&#9658;</a> <a id="doubleNextRates" class="next" href="{4}">&#9658;&#9658; </a></span></span></p>' />
                    <display:setProperty name="paging.banner.last"
                        value='<p><span id="hix-pagination"><span> <a id="doublePrevRates" class="prev" href="{1}">&#9668;&#9668;</a> <a id="singlePrevRates" class="prev" href="{2}">&#9668;</a> {0} <a id="singleNextRates" class="next" >&#9658;</a> <a id="doubleNextRates" class="next" >&#9658;&#9658; </a></span></span></p>' />
                    <display:caption media="html" class="captionHide">Rates</display:caption>
                    <display:setProperty name="paging.banner.page.separator"
                        value=" | " />
                    <display:setProperty name="paging.banner.group_size" value="4" />
                    <display:column property="age" scope="colgroup" headerScope="colgroup" title="${age}"
                        headerClass="hixTableHeader "
                        style="width: 10%;align: center;" class="displayTagtd" />
                    <display:column property="usesTobacco" scope="colgroup" headerScope="colgroup" title="${tobacco}"
                        headerClass="hixTableHeader" style="width: 30%;align: center;"
                        class="displayTagtd" />
                    <display:column property="rateAreaId" scope="colgroup" headerScope="colgroup" title="${ratingArea}"
                        headerClass="hixTableHeader" style="width: 15%;align: center;"
                        class="displayTagtd" />
                    <display:column property="rateAmount" scope="colgroup" headerScope="colgroup" title="${individualRate}"
                        headerClass="hixTableHeader"
                        style="width: 20%;align: center;" class="displayTagtd" />
                    <display:column property="individualTobaccoRate" scope="colgroup" headerScope="colgroup" title="${individualTobaccoRate}"
                        headerClass="hixTableHeader"
                        style="width: 30%;align: center;" class="displayTagtd" />
                </display:table>
    </div>

使用div并设置overflow-y和height,我可以得到一个滚动条。但是表格的标题也会滚动。如何修改标题?

我尝试了以下代码:

现在标题已修复,并且不会与正文滚动。但是每个列标题的宽度与每个列体的宽度不同。有什么方法可以解决这个问题吗?

$(document).ready(function() 
 {       scrolify($('#ratesTableDiv'), 250);
});

function scrolify(tblAsJQueryObject, height){
    var oTbl = tblAsJQueryObject;

    // for very large tables you can remove the four lines below
    // and wrap the table with <div> in the mark-up and assign
    // height and overflow property  
    var oTblDiv = $("<div/>");
    oTblDiv.css('height', height);
    oTblDiv.css('overflow-y','scroll');               
    oTbl.wrap(oTblDiv);

    // save original width
    oTbl.attr("data-item-original-width", oTbl.width());
    oTbl.find('thead tr td').each(function(){
        $(this).attr("data-item-original-width",$(this).width());
    }); 
    oTbl.find('tbody tr:eq(0) td').each(function(){
        $(this).attr("data-item-original-width",$(this).width());
    });                 


    // clone the original table
    var newTbl = oTbl.clone();

    // remove table header from original table
    oTbl.find('thead tr').remove();                 
    // remove table body from new table
    newTbl.find('tbody tr').remove();   

    oTbl.parent().parent().prepend(newTbl);
    newTbl.wrap("<div/>");

    // replace ORIGINAL COLUMN width                
    newTbl.width(newTbl.attr('data-item-original-width'));
    newTbl.find('thead tr td').each(function(){
        $(this).width($(this).attr("data-item-original-width"));
    });     
    oTbl.width(oTbl.attr('data-item-original-width'));      
    oTbl.find('tbody tr:eq(0) td').each(function(){
        $(this).width($(this).attr("data-item-original-width"));
    });                 
}

修复theader并看到tbody滚动基本上可以实现设置:tbody {display:block;height:XX;overflo:scroll;}但你在thead和tbody之间松散了单元格对齐。

您可以使用类调整此值并最终克隆页脚。如果你的标题有一些colspans,这个选项应该更好。

看一下:http://codepen.io/gcyrillus/pen/aJysI用于滚动表,其中页眉(页脚)已修复。玩代码,我相信你会理解它的用法。 :)

找到解决方案: 我使用dataTable jquery来做这件事。

首先我为表格设置了table-layout:fixed

然后在js中添加以下代码:

$("#rates").dataTable({
     "bPaginate": false,
    "sScrollY": "250px",
     "bAutoWidth": false,
     "bScrollCollapse": true,
    "sScrollX": "100%",
       "sScrollXInner": "100%",
            "bLengthChange": false,
            "bFilter":   false,
            "sDom": '<"top">rt<"bottom"flp><"clear">',
            "aoColumns": [
                          { "bSortable": false, "sWidth" : "10%" },
                          { "bSortable": true, "sWidth" : "30%" },
                          { "bSortable": true, "sWidth" : "15%" },
                          { "bSortable": true, "sWidth" : "20%" },
                          { "bSortable": true, "sWidth" : "30%" }
                          ],



}).fnAdjustColumnSizing( false );
