art-templat是在require_form.js中实现的。具体代码
html代码
{foreach name="selectdata" item="type" key="k" }
<dl data-template="answer{$k}" class="fieldlist fieldlist{$k} {$k!=0? ‘hidden‘ : ‘‘}" data-name="row[selectdata{$k}]" data-listidx="0">
<!-- k=0 单选 k=1 多选 k=2 判断 k=3 填空 k=4 简答 k=5 组合 -->
{if condition="$k eq ‘2‘"}
{foreach name="type" item="option" key="j" }
<dd class="form-inline">
<ins class="col-xs-12 col-sm-1"><input type="radio" name="row[answer{$k}]" value="{$option[‘key‘]}" /></ins>
<ins class="col-xs-12 col-sm-2"><input type="text" name="row[selectdata{$k}][{$j}][key]" class="form-control" placeholder="选项" size="10" value="{$option[‘key‘]}" {$k==2? ‘readonly‘ : ‘‘}/></ins>
<ins class="col-xs-12 col-sm-2"><input id="c-content" data-rule="required" class="form-control" name="row[selectdata{$k}][{$j}][value]" value="{$option[‘value‘]}" {$k==2? ‘readonly‘ : ‘‘}></input></ins>
<!--下面的两个按钮务必保留-->
</dd>
{/foreach}
{/if}
<!-- k=2表示是判断题，不是判断题的时候，出现追加 -->
{if condition="$k neq ‘2‘"}
<dd><a href="javascript:;" class="btn btn-sm btn-success btn-append"><i class="fa fa-plus"></i> 追加</a></dd>
{/if}
<div style="color:red;">*请选中正确答案</div>
<textarea name="row[selectdata{$k}]" class="form-control hide" cols="30" rows="5">{:json_encode($type)}</textarea>
</dl>
{/foreach}
JS代码
fieldlist: function (form) {
//绑定fieldlist
if ($(".fieldlist", form).size() > 0) {
require([‘dragsort‘, ‘template‘], function (undefined, Template) {
//刷新隐藏textarea的值
var refresh = function (name) {
var data = {};
var textarea = $("textarea[name=‘" + name + "‘]", form);
var container = $(".fieldlist[data-name=‘" + name + "‘]");
var template = container.data("template");
$.each($("input,select,textarea", container).serializeArray(), function (i, j) {
var reg = /\[(\w+)\]\[(\w+)\]$/g;
var match = reg.exec(j.name);
if (!match)
return true;
match[1] = "x" + parseInt(match[1]);
if (typeof data[match[1]] == ‘undefined‘) {
data[match[1]] = {};
}
data[match[1]][match[2]] = j.value;
});
var result = template ? [] : {};
$.each(data, function (i, j) {
if (j) {
if (!template) {
if (j.key != ‘‘) {
result[j.key] = j.value;
}
} else {
result.push(j);
}
}
});
textarea.val(JSON.stringify(result));
};
//监听文本框改变事件
$(document).on(‘change keyup changed‘, ".fieldlist input,.fieldlist textarea,.fieldlist select", function () {
refresh($(this).closest(".fieldlist").data("name"));
});
//追加控制
$(".fieldlist", form).on("click", ".btn-append,.append", function (e, row) {
var container = $(this).closest(".fieldlist");
var tagName = container.data("tag") || "dd";
var index = container.data("index");

var template = container.data("template");
var data = container.data();
index = index ? parseInt(index) : 0;
container.data("index", index + 1);
row = row ? row : {};
var vars = {index: index, name: name, data: data, row: row};
var html = template ? Template(template, vars) : Template.render(Form.config.fieldlisttpl, vars);
$(html).insertBefore($(tagName + ":last", container));
$(this).trigger("fa.event.appendfieldlist", $(this).closest(tagName).prev());
});
//移除控制
$(".fieldlist", form).on("click", ".btn-remove", function () {
var container = $(this).closest(".fieldlist");
var tagName = container.data("tag") || "dd";
$(this).closest(tagName).remove();
refresh(container.data("name"));
});
//渲染数据&拖拽排序
$(".fieldlist", form).each(function () {
var container = this;
var tagName = $(this).data("tag") || "dd";
$(this).dragsort({
itemSelector: tagName,
dragSelector: ".btn-dragsort",
dragEnd: function () {
refresh($(this).closest(".fieldlist").data("name"));
},
placeHolderTemplate: $("<" + tagName + "/>")
});
var textarea = $("textarea[name=‘" + $(this).data("name") + "‘]", form);
if (textarea.val() == ‘‘) {
return true;
}
var template = $(this).data("template");
var json = {};
try {
json = JSON.parse(textarea.val());
} catch (e) {
}
$.each(json, function (i, j) {
$(".btn-append,.append", container).trigger(‘click‘, template ? j : {
key: i,
value: j
});
});
});
});
}
},
