我使用jQuery动态生成一些表单并在jQuery对话框中显示它们。但是我的html元素没有正确创建。
我使用以下代码:
function generateEmail(to, cc, subject) {
var newDiv = $(document.createElement('div'));
newDiv.append('<form id="'+subject+'" name="'+subject+'" method="POST" action="#">');
newDiv.append('<table class="sendmail" cellpadding="0" cellspacing="0" width="100%">');
newDiv.append('<tr>');
newDiv.append('<th width="25%"><label for="to">To: </label></th>');
newDiv.append('<th width="75%"><input type="text" id="to'+subject+'" name="to" class="text small sendmail" value="'+to+'" /></th>');
newDiv.append('</tr>');
newDiv.append('<tr>');
newDiv.append('<th width="25%"><label for="cc">CC: </label></th>');
newDiv.append('<th width="75%"><input type="text" id="cc'+subject+'" name="cc" class="input" value="'+cc+'" /></th>');
newDiv.append('</tr>');
newDiv.append('<tr>');
newDiv.append('<th width="25%"><label for="subject">Subject: </label></th>');
newDiv.append('<th width="75%"><input type="text" id="sj'+subject+'" name="subject" class="input" value="'+subject+'" /></th>');
newDiv.append('</tr>');
newDiv.append('<tr>');
newDiv.append('<th width="25%"><label for="message">Message: </label></th>');
newDiv.append('<th width="75%"></th>');
newDiv.append('</tr>');
newDiv.append('<tr>');
newDiv.append('<th colspan="2"><textarea name="message">email body</textarea></th>');
newDiv.append('</tr>');
newDiv.append('</table>');
newDiv.append('</form>');
$(newDiv).dialog({
modal: true,
title: "Reply to "+subject,
height: 400,
width: 700,
buttons: [
{
text: "Cancel",
click: function() {
$(this).dialog("close");
}},
{
text: "Send",
click: function() {
if($('#to'+subject).val() == ''){
alert('empty');
}
//$('#zFormer').submit();
}}
]
});
}
但我得到的结果是:
<div class="ui-dialog-content ui-widget-content" style="display: block; width: auto; min-height: 0px; max-height: none; height: 289px;" id="ui-id-1">
<form id="SDS19272N63023" name="SDS19272N63023" method="POST" action="#"></form>
<table class="sendmail" width="100%" cellpadding="0" cellspacing="0"></table>
<tr></tr><th width="25%"><label for="to">To: </label></th><th width="75%"><input id="toSDS19272N63023" name="to" class="text small sendmail" value="email@gmail.com" type="text"></th>
<tr></tr><th width="25%"><label for="cc">CC: </label></th><th width="75%"><input id="ccSDS19272N63023" name="cc" class="input" value="" type="text"></th>
<tr></tr><th width="25%"><label for="subject">Subject: </label></th><th width="75%"><input id="sjSDS19272N63023" name="subject" class="input" value="SDS19272N63023" type="text"></th>
<tr></tr><th width="25%"><label for="message">Message: </label></th><th width="75%"></th>
<tr></tr><th colspan="2"><textarea name="message">email body</textarea></th>
</div>
如您所见,这些HTML元素未正确生成。我对此完全感到困惑。任何人都知道为什么?
我正在使用jQuery v1.10.2和jQuery UI - v1.10.4。
谢谢!

创建一个HTML字符串,然后将该HTML字符串传递给追加函数,如下所示
var newDiv = $(document.createElement('div'));
var HtmlStr = '<form id="'+subject+'" name="'+subject+'" method="POST" action="#">';
HtmlStr += '<table class="sendmail" cellpadding="0" cellspacing="0" width="100%">';
HtmlStr += '<tr>';
HtmlStr += '<th width="25%"><label for="to">To: </label></th>';
HtmlStr += '<th width="75%"><input type="text" id="to'+subject+'" name="to" class="text small sendmail" value="'+to+'" /></th>';
HtmlStr += '</tr>';
HtmlStr += '<tr>';
HtmlStr += '<th width="25%"><label for="cc">CC: </label></th>';
HtmlStr += '<th width="75%"><input type="text" id="cc'+subject+'" name="cc" class="input" value="'+cc+'" /></th>';
HtmlStr += '</tr>';
HtmlStr += '<tr>';
HtmlStr += '<th width="25%"><label for="subject">Subject: </label></th>';
HtmlStr += '<th width="75%"><input type="text" id="sj'+subject+'" name="subject" class="input" value="'+subject+'" /></th>';
HtmlStr +='</tr>';
HtmlStr += '<tr>';
HtmlStr += '<th width="25%"><label for="message">Message: </label></th>';
HtmlStr +='<th width="75%"></th>';
HtmlStr += '</tr>';
HtmlStr += '<tr>';
HtmlStr += '<th colspan="2"><textarea name="message">email body</textarea></th>';
HtmlStr +='</tr></table> </form>';
newDiv.append(HtmlStr);

jQuery auto会自动完成您使用append
放入的所有不完整标记(如何知道您稍后会附加结束标记),因此您需要将其全部一行并执行一个{{ 1}}陈述。要么或者附加在表单标签中,要获取该表单元素,然后将元素追加到该表单中(并为所有元素重复该过程)
所以这个:
append
或者这个:
newDiv.append('<form id="'+subject+'" name="'+subject+'" method="POST" action="#"><table class="sendmail" cellpadding="0" cellspacing="0" width="100%"><tr><th width="25%"><label for="to">To: </label></th><th width="75%"><input type="text" id="to'+subject+'" name="to" class="text small sendmail" value="'+to+'" /></th></tr><tr><th width="25%"><label for="cc">CC: </label></th><th width="75%"><input type="text" id="cc'+subject+'" name="cc" class="input" value="'+cc+'" /></th></tr><tr><th width="25%"><label for="subject">Subject: </label></th><th width="75%"><input type="text" id="sj'+subject+'" name="subject" class="input" value="'+subject+'" /></th></tr><tr><th width="25%"><label for="message">Message: </label></th><th width="75%"></th></tr><tr><th colspan="2"><textarea name="message">email body</textarea></th></tr></table></form>');
