我想将以下输入字段转换为嵌套的json文件结构,如下所示在我的html页面中,我尝试了几种方法,但无法获得。在这里,我通过angularjs ng-repeat获得这些输入。请帮助我,我该如何实施。提前谢谢。
col
正如我在普通的json结构中得到的那样:
<form id="text" method="post" action="" enctype="multipart/form-data">
<input type="hidden" value="/images/Image1.nii" name="imageurl">
<input type="hidden" value="3d0" name="3d" >
<input type="hidden" value="sliceX0" name="sliceX">
<input type="hidden" value="sliceY0" name="sliceY">
<input type="hidden" value="sliceZ0" name="sliceZ">
<input type="hidden" value="/images/Image2.nii" name="imageurl">
<input type="hidden" value="3d1" name="3d1" >
<input type="hidden" value="sliceX1" name="sliceX">
<input type="hidden" value="sliceY1" name="sliceY">
<input type="hidden" value="sliceZ1" name="sliceZ">
</form>
但我需要如下:
[{"name":"imageurl","value":"/images/Image1.nii"},{"name":"3d","value":"3d0"},{"name":"sliceX","value":"sliceX0"},{"name":"sliceY","value":"sliceY0"},{"name":"sliceZ","value":"sliceZ0"},{"name":"imageurl","value":"/images/Image2.nii"},{"name":"3d","value":"3d1"},{"name":"sliceX","value":"sliceX1"},{"name":"sliceY","value":"sliceY1"},{"name":"sliceZ","value":"sliceZ1"}]
如何使用jquery
将表单输入字段转换为嵌套的json结构答案 0 :(得分:1)
您应该使用lodash之类的帮助程序库来执行此类数据操作。
这是我用lodash做的转换:
// split the data into chunks of 5 elements each
var chunks = _.chunk(data, 5);
// for every chunk create the desired object with the parts
var desired = _.map(chunks, function(c) {
var image = c[0];
image.parts = _.rest(c);
return image;
});
console.log(desired);
这是一个有效的Plunker

您应该将每个图像组包装在自己的容器中。但是如果你必须保持目前的结构:
var el = document.querySelectorAll('#text [type="hidden"]');
var arr = [];
var obj = {};
var push = false;
for(var i = 0; i < el.length; i ++){
if(el[i].value.indexOf('images') > -1){
if(push){
arr.push(obj);
obj = {};
};
obj.name = 'imageurl';
obj.value = el[i].value;
push = true;
}
obj.parts = obj.parts || [];
obj.parts.push({
name: el[i].name,
value: el[i].value
});
}
