Question

我正在尝试调用一个函数，该函数将一个非常长的html字符串写入元素。该字符串看起来与此类似;

   '<div id='gaugearray8'>
<p id='ANCPUB' class='plot' style='height:100px;width:175px;float:left;' title='0.0011217599587192' onClick=LowerLevelPrint([{"NumberSelected":1,"TargetPerc":[237.5],"KpiDescription":["Contribution&nbspof&nbspExternal&nbspRevenue"],"KpiName":["revcontrubionkpi"],"ValuetoPrint":[0.0011217599587192],"ValueNow":[19],"ValueCompare":[1693767],"Target":["8"],"KpiUnits":["Pounds"],"PercentCompare":[0.0011217599587192]}]) onmouseover=TopLevelLabel({"NumberSelected":1,"Description":["Contribution&nbspof&nbspExternal&nbspRevenue"],"GroupDescription":"Ancillary&nbspService&nbspPerformance"}) onmouseout=clearnew()></p>
<p id='CSPUB' class='plot' style='height:100px;width:175px;float:left;' title='21.855170547342' onClick=LowerLevelPrint([{"NumberSelected":7,"TargetPerc":[206.03360584712,8.8767313176762,10.356186537289,12.5,12.5,237.5,10.356186537289],"KpiDescription":["Operating&nbspCost&nbspper&nbspService&nbspKm","Revenue&nbspper&nbspService&nbspKm","Total&nbspCost&nbspper&nbspService&nbspKm","Claims&nbspCost&nbspper&nbspVehicle","Claims&nbspCost&nbspper&nbspDriver","Number&nbspof&nbspClaims&nbspLodged&nbspper&nbsp100,000km","Overheads&nbspCost&nbspper&nbspService&nbspKm"],"KpiName":["opcostperkmkpi","revenueperkmkpi","totalcostperkmkpi","claimspervehkpi","claimsperdriverkpi","claimslodgedkpi","overheadskpi"],"ValuetoPrint":[110.47252736225,5.6435200058102,5.434671444334,0.35610369406272,0.35829645079956,12.666666666667,18.054408207469],"ValueNow":[10.301680292356,0.62137119223733,0.62137119223733,1,1,19,0.62137119223733],"ValueCompare":[9.32510601353,11.010348002623,11.433463800009,280.81708128079,279.09849449204,150,3.4416591510336],"Target":["5","7","6","8","8","8","6"],"KpiUnits":["Pounds&nbspper&nbspKm","Pounds&nbspper&nbspKm","Pounds&nbspper&nbspKm","Pounds&nbspper&nbspVehicle","Pounds&nbspper&nbspDriver","Claims","Pounds&nbspa&nbspkm"],"PercentCompare":[110.47252736225,5.6435200058102,5.434671444334,0.35610369406272,0.35829645079956,12.666666666667,18.054408207469]}]) onmouseover=TopLevelLabel({"NumberSelected":7,"Description":["Operating&nbspCost&nbspper&nbspService&nbspKm","Revenue&nbspper&nbspService&nbspKm","Total&nbspCost&nbspper&nbspService&nbspKm","Claims&nbspCost&nbspper&nbspVehicle","Claims&nbspCost&nbspper&nbspDriver","Number&nbspof&nbspClaims&nbspLodged&nbspper&nbsp100,000km","Overheads&nbspCost&nbspper&nbspService&nbspKm"],"GroupDescription":"Core&nbspService&nbspPerformance"}) onmouseout=clearnew()></p>
<p id='ROPTUB' class='plot' style='height:100px;width:175px;float:left;' title='9.7292765723395' onClick=LowerLevelPrint([{"NumberSelected":2,"TargetPerc":[12.5,207.23684210526],"KpiDescription":["Revenue&nbspExpenditure&nbspper&nbspPassenger&nbspJourney","Cost&nbspPer&nbspHeadcount"],"KpiName":["revexperjourneykpi","coststaffkpi"],"ValuetoPrint":[19.044041148259,0.41451199641943],"ValueNow":[1,16.578947368421],"ValueCompare":[5.2509863437855,3999.6302909519],"Target":["8","8"],"KpiUnits":["Pounds&nbspper&nbspJourney","Pounds&nbspper&nbspStaff"],"PercentCompare":[19.044041148259,0.41451199641943]}]) onmouseover=TopLevelLabel({"NumberSelected":2,"Description":["Revenue&nbspExpenditure&nbspper&nbspPassenger&nbspJourney","Cost&nbspPer&nbspHeadcount"],"GroupDescription":"Resource&nbspOptimisation"}) onmouseout=clearnew()></p></div>';

不要担心会因为它只是一个可以发送的内容的例子。我假设问题是这个字符串中有多个引号，因为当我包含这个函数时，页面上的javascript完全停止工作。

上面的字符串实际上是在php循环中生成的，而我正在尝试使用的函数调用

 document.getElementById('financearea').innerHTML = 
   '<?php $myview->PopulateContent($finance, 8, 'ub', 'UB', $a); ?>';

` 它在主页面中正常工作，但在使用innerHTML方法时不会运行。

有没有人对如何运作有任何建议？

这是php端的代码 - 它在循环中创建并回显

$thisgoesinfile = "<p id='".$Group.$Depot."' class='plot' style='height:100px;width:175px;float:left;' title='".$TotalValuetoPrint."' onClick=LowerLevelPrint(".json_encode($result_set).") onmouseover=TopLevelLabel(".json_encode($Descriptions).") onmouseout=clearnew()></p>";

编辑：我尝试删除php字符串中的所有单引号，所以现在字符串看起来像

但仍然没有工作。

Answer 1

使用json_encode而不是自己用单引号包装文本：

document.getElementById('financearea').innerHTML = <?php echo json_encode($myview->PopulateContent($finance, 8, 'ub', 'UB', $a)); ?>;

当你将一个字符串传递给json_encode时，它将被包装在引号中，并且其中的任何引号和其他特殊字符将被正确编码以用作JavaScript文字字符串。（这是JSON是JavaScript的文字语法的子集这一事实的副产品。）

（我还在那里添加了echo;我不是一个PHP头，所以如果不需要它就删除它，但是你没有使用短标签，所以... ）

Answer 2

转义PHP输出中的单引号！ :)

替换'with \'

Answer 3

显然你需要确保你在字符串中转义引号或者Javascript会中断。一个简单的解决方案是在字符串中使用双引号，并使用单引号分隔字符串。

'<div id="gaugearray8">'

使用innerhtml编写带有大量引号的html
