Drupal 7 更新文档上写到：
Javascript should be made compatible with other libraries than jQuery by adding a small wrapper around your existing code:
这是为了兼容其他的JAVASCRIPT这样做的，
有一个办法可以解决：
(function ($) {
// Original JavaScript code.
})(jQuery);
?
可以使用闭包解决
The $ global will no longer refer to the jquery object. However, with this construction,
the local variable $ will refer to jquery, allowing your code to access jQuery through $ anyway,
while the code will not conflict with other libraries that use the $ global.
(function ($) {
// Create the tooltips only on document load
$(document).ready(function() {
// By suppling no content attribute, the library uses each elements title attribute by default
$('#content a[href]').qtip({
// Simply use an HTML img tag within the HTML string
content: 'dfdfdfdfdf'
});
});
})(jQuery);
