Which characters need to be escaped in HTML?

阅读更多关于 Which characters need to be escaped in HTML?

问题 Are they the same as XML, perhaps plus the space one ( )? I've found some huge lists of HTML escape characters but I don't think they must be escaped. I want to know what needs to be escaped. 回答1: If you're inserting text content in your document in a location where text content is expected 1 , you typically only need to escape the same characters as you would in XML.

问题 I want to be able to pass any string to the buttons text in JQuery UI. Suppose I have this string: Ajouter L'amie a la liste "amies" The only way to actually pass this text without causing a massive JavaScript error is by HTML-encoding it. registerhtml.dialog({ modal: true, title: 'My Dialog Title', resizable: false, buttons: [ { text: 'Ajouter L'amie a la liste "amies"', click: function(){ // Do something important $(this).dialog('close'); } }, { text: 'Cancel', click: function() { $(this)

问题 I have received some XML from an upstream data source. I'm not sure if these weird characters are valid UTF8 -or- the upstream source has messed things up. i.e. Bad data in => bad data out.
