最近在定义bootstrap 页面的时候 ,  在订制一版本之后想更新的版本  但是需要看以前的conig.json 一一设置 感觉非常麻烦  于是就看了一下他的页面结构  专门写了一个JS 用于加载上一版本的配置 然后在此基础之上订制新的版本

var config = {		  "vars": {			    "@font-size-base": "13px",			    "@grid-gutter-width": "10px",			    "@padding-base-vertical": "4px",			    "@alert-padding": "8px",			    "@navbar-height": "43px",			    "@nav-link-padding": "5px 8px",			    "@table-cell-padding": "5px",			    "@table-condensed-cell-padding": "2px",			    "@modal-inner-padding": "10px",			    "@modal-title-padding": "8px"			  },			  "css": [			    "print.less",			    "type.less",			    "code.less",			    "grid.less",			    "tables.less",			    "forms.less",			    "buttons.less",			    "glyphicons.less",			    "button-groups.less",			    "input-groups.less",			    "navs.less",			    "navbar.less",			    "breadcrumbs.less",			    "pagination.less",			    "pager.less",			    "labels.less",			    "badges.less",			    "jumbotron.less",			    "thumbnails.less",			    "alerts.less",			    "progress-bars.less",			    "media.less",			    "list-group.less",			    "panels.less",			    "wells.less",			    "close.less",			    "dropdowns.less",			    "tooltip.less",			    "popovers.less",			    "modals.less",			    "carousel.less",			    "utilities.less",			    "responsive-utilities.less",			    "component-animations.less"			  ],			  "js": [			    "alert.js",			    "button.js",			    "carousel.js",			    "dropdown.js",			    "modal.js",			    "tooltip.js",			    "popover.js",			    "tab.js",			    "affix.js",			    "collapse.js",			    "scrollspy.js",			    "transition.js"			  ]			};var vars = config.vars;var csses = config.css;var jses = config.js;for ( var key in vars) {	var value = vars[key];	$("input[data-var='"+key+"']").val(value);}for ( var key in csses) {	$("input[value='"+csses[key]+"']").get(0).checked = true;}for ( var key in jses) {	console.log($("input[value='"+jses[key]+"']"));	$("input[value='"+jses[key]+"']").get(0).checked = true;}
