PHP块似乎单调乏味重复的PHP块的下拉选项列表中的每一个选项,因为在这种情况下:环路周围选择HTML选项,并添加每个
<select name="religion" id="relaff" onchange="changeList(this)">
<option <?php if($religion == "Paganism"){echo " selected=\"Paganism\"";} ?> value="Paganism">Paganism</option>
<option <?php if($religion == "Wicca"){echo " selected=\"Wicca\"";} ?> value="Wicca">Wicca</option>
<option <?php if($religion == "Witchcraft"){echo " selected=\"Witchcraft\"";} ?> value="Witchcraft">Witchcraft</option>
<option <?php if($religion == "Islam"){echo " selected=\"Islam\"";} ?> value="Islam">Islam</option>
<option <?php if($religion == "Buddhism"){echo " selected=\"Buddhism\"";} ?> value="Buddhism">Buddhism</option>
<option <?php if($religion == "No religion"){echo " selected=\"No religion\"";} ?> value="No religion">No religion</option>
<option <?php if($religion == "Christianity"){echo " selected=\"Christianity\"";} ?> value="Christianity">Christianity</option>
<option <?php if($religion == "Other"){echo " selected=\"Other\"";} ?> value="Other">Other</option></select>
这是因为在最坏的情况下同样的形式,我有另一个下拉菜单,根据在上面编码的下拉列表中选择的内容自动生成一个值。这里是第二个下拉菜单相关的上述之一:
<select name="denomination" id="reldet">
<option
<?php echo " selected=" . $denomination . ""; ?>
value="NONE">This will update after selecting a religion</option></select>
有人可以帮我解决这个问题吗?这似乎令人困惑。 编辑:具有功能的变更表的JS文件是在这里:
var lists = new Array();
lists['Select religion'] = new Array();
lists['Select religion'][0] = new Array(
'This will update after selecting a religion'
);
lists['Select religion'][1] = new Array(
''
);
// First set of text and values
lists['Paganism'] = new Array();
lists['Paganism'][0] = new Array(
'Hellenic',
'Asatru',
'Roman',
'Celtic'
);
lists['Paganism'][1] = new Array(
'Hellenic',
'Asatru',
'Roman',
'Celtic'
);
// Second set of text and values
lists['Wicca'] = new Array();
lists['Wicca'][0] = new Array(
'Gardnerian',
'Eclectic',
'Inclusive',
'Solitary'
);
lists['Wicca'][1] = new Array(
'Gardnerian',
'Eclectic',
'Inclusive',
'Solitary'
);
lists['Witchcraft'] = new Array();
lists['Witchcraft'][0] = new Array(
'British Traditional',
'Santeria',
'Voodoo'
);
lists['Witchcraft'][1] = new Array(
'British Traditional',
'Santeria',
'Voodoo'
);
lists['Christianity'] = new Array();
lists['Christianity'][0] = new Array(
'Catholic',
'Aglipayan',
'Protestant',
'Pentecostal',
'Baptist',
'Methodist',
'Iglesia Ni Cristo',
'Latter-Day Saints (Mormons)',
'Seventh-Day Adventist',
// string escape method here
'Jehovah\'s Witnesses'
);
lists['Christianity'][1] = new Array(
'Catholic',
'Aglipayan',
'Protestant',
'Pentecostal',
'Baptist',
'Methodist',
'Iglesia Ni Cristo',
'Latter-Day Saints (Mormons)',
'Seventh-Day Adventist',
// string escape method here
'Jehovah\'s Witnesses'
);
lists['Other'] = new Array();
lists['Other'][0] = new Array(
'Judaism',
'Sikhism',
'Shintoism'
);
lists['Other'][1] = new Array(
'Judaism',
'Sikhism',
'Shintoism'
);
lists['No religion'] = new Array();
lists['No religion'][0] = new Array(
'Atheist',
'Agnostic'
);
lists['No religion'][1] = new Array(
'Atheist',
'Agnostic'
);
// This function goes through the options for the given
// drop down box and removes them in preparation for
// a new set of values
function emptyList(box) {
// Set each option to null thus removing it
while (box.options.length) box.options[0] = null;
}
// This function assigns new drop down options to the given
// drop down box from the list of lists specified
function fillList(box, arr) {
// arr[0] holds the display text
// arr[1] are the values
for (i = 0; i < arr[0].length; i++) {
// Create a new drop down option with the
// display text and value from arr
option = new Option(arr[0][i], arr[1][i]);
// Add to the end of the existing options
box.options[box.length] = option;
}
// Preselect option 0
box.selectedIndex=0;
}
// This function performs a drop down list option change by first
// emptying the existing option list and then assigning a new set
function changeList(box) {
// Isolate the appropriate list by using the value
// of the currently selected option
list = lists[box.options[box.selectedIndex].value];
// Next empty the slave list
emptyList(box.form.denomination);
// Then assign the new list values
fillList(box.form.denomination, list);
}
首先查看代码中选定的属性,并将其与http://www.w3schools.com/tags/tag_option.asp上的文档进行比较。提示:选定的属性只有一个“选定”作为值。 changeList()javascript函数是什么?你能提供任何代码吗? 第二个下拉菜单中的php代码令人困惑。 <?php标记之前的$面值是什么? – Marcel
我刚刚添加了JavaScript代码。 $面额是一个错字。我会解决这个问题。 – kureidothephpsniper
