ExtJS4插件EditArea

EditArea是一个支持语法高亮的文本编辑器,同类软件还有Ace, CodeMirror等。具体功能方面的差异,请访问http://en.wikipedia.org/wiki/Comparison_of_JavaScript-based_source_code_editors。 

项目中用到ExtJS 4.2和EditArea,由于找不到EditArea插件,因此自己实现了一个,经测试基本可用。实现过程仿照已有插件,比较简单,不再啰嗦。 

     

Ext.define('Ext.ux.form.EditTextArea', {  
    extend: 'Ext.form.TextArea',  
    alias: 'widget.editarea',  
      
    initComponent: function() {  
        var me = this;  
        this.eaid = this.id;  
        me.callParent(arguments);  
        editAreaLoader.init({  
                id: this.eaid,  
                start_highlight: this.initialConfig.start_highlight || true,  
                language: this.initialConfig.language|| 'en',  
                syntax: this.initialConfig.syntax,  
                syntax_selection_allow: "css,html,js,php,python,vb,xml,c,cpp,sql,basic,pas,brain",  
                allow_toggle: this.initialConfig.allow_toggle || true,  
                allow_resize: this.initialConfig.allow_resize || false,  
                replace_tab_by_spaces: this.initialConfig.replace_tab_by_spaces || 4,  
                toolbar: this.initialConfig.toolbar || "search, go_to_line, |, undo, redo, |, select_font,|, change_smooth_selection, highlight, reset_highlight, |, help",  
                is_editable: this.initialConfig.is_editable || true,  
                show_line_colors: true,  
                //plugins: "autocomplite",  
                autocompletion:true  
            });  
    },  
      
    afterRender: function() {  
        this.callParent();  
    },  
      
    getValue:function(){  
        var v = editAreaLoader.getValue(this.eaid);  
        return v;  
    },  
          
    setValue: function(value) {  
        editAreaLoader.setValue(this.eaid, value);  
    },  
    onDestroy: function() {  
        editAreaLoader.delete_instance(this.eaid);  
        this.callParent();  
    }  
});
