listElement = $(“<li>”, {class: “ui-state-default”, text: newText, ‘data-value’: newValue});
if (elementAlreadyExists(newValue)){

} else {

}
});

Now I want create a form just like that.
Here is the code of the function test_form
[code=php]
$css = ”
#sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
#sortable li { margin: 0 5px 5px 5px; padding: 5px; font-size: 1.2em; height: 1.5em; }
html>body #sortable li { height: 1.5em; line-height: 1.2em; }
.ui-state-highlight { height: 1.5em; line-height: 1.2em; }
div{ padding: 10px; }
#addButton
{
background-image:url(add_btn.png);
width:18px;
height:18px;
}
“;
$js = ”
function elementAlreadyExists(val){
var elementAlreadyExists = false;
$(“#sortable > li”).each(function(){
var currVal = $(this).data(“value”);
if(currVal === val){
elementAlreadyExists = true;
return;
}
});
return elementAlreadyExists;
}
$(“#sortable”).sortable({ placeholder: “ui-state-highlight” }).disableSelection();
$(“#addButton”).on(“click”, function(){
var s1 = $(“.category-select”).eq(0).find(“option:selected”),
s2 = $(“.category-select”).eq(1).find(“option:selected”),
newText = s1.text() + ” – ” + s2.text();
newValue = s1.val() + “-” + s2.val();
listElement = $(“<li>”, {class: “ui-state-default”, text: newText, ‘data-value’: newValue});
if (elementAlreadyExists(newValue)){
alert(“Already Exists!”);
} else {
$(“#sortable”).append(listElement);
}
});
“;

);
$form[‘remote_projects’] = array(
‘#type’ => ‘select’,
‘#title’ => t(‘Remote Projects’),
‘#options’ => $remote_projects, //remote_projects contains many key=>value pairs
//’#default_value’ => $category[‘selected’],
‘#description’ => t(‘Choose a Remote project’),
‘#attributes’ => array(‘class’ => array(‘category-select’)),
);
$form[‘addButton’] = array(
‘#attributes’ => array(‘style’ => ‘display: inline-block;’),
‘#type’ => ‘link’,
‘#title’ => t(”),
‘#href’ => “#”,
‘#id’ => ‘addButton’,
);
$form[‘sortable’] = array(
‘#id’ => ‘sortable’,
‘#type’ => ‘#ul’,
);
return system_settings_form($form);
5 issues occurred:
– The style code is wrapped in CDATA tag.
– The js code is wrapped in CDATA tag.
– The add button image (file add_btn.png) can not show, despite it already existing in both the folders of the module and the site’s root directory.
– The comboboxes display in 2 different rows, instead of only one row.
– The hash character of the add button image’s href property turns to “%23” when the page loads.
Please tell me what should I do to fix these problems? What change should I make to the code? It seems to me that my css and js script could not work.
