我试图找到一种方法来填充多种选项类型,选择,无线电,texareas,复选框的表单。我发现很少有像jQuery填充插件或建议的脚本Using jQuery and JSON to populate forms?以及更多的堆栈帖子,但它们都没有正确处理多维JSON数据。这是我正在处理的JSON数据的小样本,
var jsonData = {
"get_template": "clean",
"site_width": "1200px",
"layout_type": "full",
"main_contained": {
"picked": "contained",
"notcontained": {
"container_contained": "contained"
}
},
"container_spacing": "25",
"columns_spacing": "25",
"sidebars_spacing": {
"horizontal": "50",
"vertical": "50"
},
"headers": "menuright",
"menu_template": "menuinheader",
"toplevel_font": {
"font": "Open Sans|600|latin|uppercase|default",
"size": "12",
"letterspacing": "0",
"css": "font-family:'Open Sans',sans-serif;font-weight:600;font-style:normal;font-size:12px;text-transform:uppercase;",
"google_font_link": "Open Sans:600&subset=latin"
},
"sublevel_font": {
"font": "Open Sans|regular|latin|none|default",
"size": "14",
"letterspacing": "0",
"css": "font-family:'Open Sans',sans-serif;font-weight:normal;font-style:normal;font-size:14px;",
"google_font_link": "Open Sans:regular&subset=latin"
},
"footer_switch": 1,
"show_button": {
"picked": "hide",
"show": {
"button": {
"button_text": "Load more",
"html": "<div class=\"btn-container grid-item-more\"><a class=\"button btn-small radius-4 btn-border-1 align-center btn-trans\" href=\"#\"><span class=\"btn-text fs-13 fw-600\">more</span></a></div>",
"json": "{\"createButton\":\"on\",\"buttonTransition\":\"on\",\"buttonAnimation\":false}"
}
}
},
"img-smaller": {
"max-width": "260",
"max-height": "145"
},
"img-xsmall": {
"max-width": "120",
"max-height": "65"
},
"img-related": {
"max-width": "350",
"max-height": "350"
},
"custom_css": 0,
"disable_admin_bar": false,
"footer_section": {
"json": "[{\"type\":\"section\",\"shortcode\":\"section_e603095\",\"width\":\"\",\"_items\":[{\"type\":\"columns\",\"shortcode\":\"columns_a9ae4ee\",\"width\":\"1_3\",\"options\":{\"widget_name\":\"Widget 1\",\"widget_in_boxstyle\":{\"padding\":{\"top\":\"0\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\"}]"
}
};
并且您可以看到表单可以包含text,json,booleans等值。
表单输入名称的前缀为fw_options[link_color]
或fw_options[main_contained][picked]
如果我至少找不到一种方法来正确循环通过这个json以正确的方式重建输入名称,我可能只需检查输入类型并设置其值。 < / p>
感谢任何帮助。

不幸的是,代码会很乱,但这就是你需要做的事情。
弄清楚如何为所有这些循环,不幸的是我只能建议你用一个孩子调用自己的地方,如下面的代码使用模拟变量:
function jsonloop(looper){ //pass in object/array to loop through
//code
if(lastchild){ //if last child of the lower part
upperchild++; //go to next child of upper part
jsonloop(upperchild);
}
}
使用instanceof
检查类型:
if(json instanceof Array){
for(var item in json){
var jsonarray = json[item];
//do stuff
}
} else if(json instance of Object){
for(var item in json){
var jsonobject = json[item];
//do different stuff like below
for(var name in jsonobject){ //loop through object properties
//do other stuff
}
}
}
这是所有模拟代码!
不要使用它,它不会很好地结束。注意:最终结果可能是半大量的,因为像"json": [{}]
这样的东西既是对象又是数组,而你的代码将会轰炸。这是一些很好的资源:
