我想从javascript中添加一个新的div到我现有的html页面。通常我用指令document.createElement(“div”)来做到这一点,我用方法div.innerHTML =“”填充这个div(例如)。这在大多数情况下工作正常,但现在我想添加一个选择列表到我的div并填充这些列表的一些数据。此方法不起作用:通过javascript与新创建的html进行交互
function initEdit(){
addPanel = document.createElement("div");
addPanel.innerHTML = "<form id='addProperty' method='get'> <table>" +
"<tr> <td> <select size='4' style='width:140px; height:200px' id='object_property_selection' onClick='unSelect(\"data_property_selection\")'> </td>" +
"<td> <select size='4' style='width:140px; height:200px' id='object_selection'>" +
"<textarea style='width:140px; height:200px; display:none' id='data_selection' /> </td> </tr>" +
"<tr> <td> <select size='4' style='width:140px; height:100px' id='data_property_selection' onClick='unSelect(\"object_property_selection\")'> </td>" +
"<td> </td> </tr>" +
"<tr> <td colspan=2> <input type='button' name='Submit' style='width:100%' onClick='submitProperty()' /> </td> </tr>" +
"</table> </form>";
$('body').jAlert(contents, 'info', offset);
list1.forEach(function(element, id){
var option = document.createElement("OPTION");
option.text = option.value = property;
form.data_property_selection.options.add(element);
})
}
有没有人知道如何解决这个问题? (顺便说一句:我不能在一开始设定在这个页面的html代码,因为这是一个jAlert div的内容)
更新:解决
properties1.concat(properties2).forEach(function(property, id){
if (id < object_properties.length) propertyList1 += "<option value='" + property + "'>" + property + "</option>";
else propertyList2 += "<option value='" + property + "'>" + property + "</option>";
})
objects.forEach(function(feature, id) {
objectList += "<option value='" + feature._id + "'>" + feature.name + "</option>";
})
propertyList = "<form id='addProperty' method='get'> <table>" +
"<tr> <td> <select size='4' style='width:140px; height:200px' id='object_property_selection' onClick='unSelect(\"data_property_selection\")'>" +
propertyList1 + "</select> </td>" +
"<td> <select size='4' style='width:140px; height:200px' id='object_selection'>" +
objectList + "</select> </td>" +
"<textarea style='width:140px; height:200px; display:none' id='data_selection' /> </td> </tr>" +
"<tr> <td> <select size='4' style='width:140px; height:100px' id='data_property_selection' onClick='unSelect(\"object_property_selection\")'>" +
propertyList2 + "</select> </td>" +
"<td> </td> </tr>" +
"<tr> <td colspan=2> <input type='button' name='Submit' style='width:100%' onClick='submitProperty()' /> </td> </tr>" +
"</table> </form>";
您似乎实际上并未将创建的div添加到页面中。你不需要document.body.appendChild(addPanel)吗? – 2012-04-16 17:54:27

使用的内容尝试查看jQuery委托函数,它允许访问js生成的DOM – 2012-04-16 18:08:46
