一、jq动态拼接html页面
需求:
1.页面内容不是死的
2.根据后台数据动态加载页面数据
实现:
在这之前我们需要了解下apppend()与html()这两个方法的区别:
简单来说就是append（）方法是在元素列表添加某个元素，但是html（）是替换元素中的数据。如果需要做换页，导航此类的效果最好使用html（）方法
详情可参考:append()与html()区别
废话不多说直接上代码:
1.首先 在需要动态拼接的地方的父级标签可以加上一个id或者class类名 区别倒是不大 个人都是加className 如下(templateArea即是 我们会在其下面拼接html页面及数据):
<body>
<div class="page">
<div class="tab_line clearfix">
<a class="tab_line_a" href="/reportPage?mainId=${mainId !}&year=${year !}&isFillIn=${mainId !}">医疗质量</a>
<a class="tab_line_a" href="/reportPageOperate?mainId=${mainId !}&year=${year !}&isFillIn=${isFillIn !}">运营效率</a>
<a class="tab_line_a now_a">持续发展</a>
<a class="tab_line_a" href="/reportPageSatisface?mainId=${mainId !}&year=${year !}&isFillIn=${isFillIn !}">满意度</a>
</div>
<div class="templateArea">
</div>
<div class="bottom">
<a href="/homepage" class="operation_line_button fr">返回</a>
<div class="operation_line_button operation_line_button_blue fr save">保存</div>
</div>
</div>
</body>
2.ajax获取到数据 根据数据情况和需求可自主选择拼接流程 以下为我个人需求拼接:
主要步骤为:
a.新建变量用来存放页面 即:var list=""
b.将对应页面放到list中 如需要放一个input 则为:list+=“input标签” 主要就是这种格式
c.最后就是$(".templateArea").append(list)
大概就是这三步 但是需求都是不一样的 所以说根据自己情况进行改动 有这个思路就可
function getTemplateList(param) {
jQuery.ajax({
url: systemBaseInterface + "/sustainedAdd/findSustainedTemplateList",
type: "POST",
cache: false,
async: false,
data: param,
dataType: "json",
success: function (data, text) {
var list = "";
for (var i = 0; i < data.data.length; i++) {
if (i == 0) {
list += "<div class=\"content\">\n" +
" <div class=\"title\">" + data.data[i].content + "<span style=\"float: right\">" + ${year !} + "</span></div>\n" +
" <table class=\"content_table\">\n" +
" <tr>\n" +
" <th></th>\n" +
" <th></th>\n" +
" <th></th>\n" +
" <th></th>\n" +
" </tr>"
} else {
list += "<div class=\"content\">\n" +
" <div class=\"title\">" + data.data[i].content + "\n" +
" </div>\n" +
"<table class=\"content_table functionalPositionArea\">\n" +
" <tr>\n" +
" <th></th>\n" +
" <th></th>\n" +
" <th></th>\n" +
" <th></th>\n" +

}
jQuery.ajax({

data: {"parentCode": data.data[i].code},
dataType: "json",
success: function (data, text) {
for (var j = 0; j < data.data.length; j++) {
var content = JSON.parse(htmlDecode(data.data[j].content))
if (content.threeType == "定性") {
list += " <tr>\n" +
" <td class=\"content_table_label\">" + content.threeName + "</td>\n" +
" <td colspan=\"3\">\n" +

}
list += " </ul>\n" +
" </div>\n" +
" </div>\n" +
" </td>\n" +
" </tr>"
} else if (content.threeType == "定量") {
for (var k = 0; k < content.tiaojian.length; k++) {
if (k == 0) {
var kk = k + 1;
list += " <tr>\n" +
" <td class=\"content_table_label\" rowspan=" + content.tiaojian.length + ">" + content.threeName + "</td>\n" +

$(".templateArea").append(list)

})

这里是我的拼装代码 我是分三种情况进行拼接的 因需求而异 这种方法笨是笨了点 不过身为后台开发的 有时候想不到思路的话这种拼接倒也不失为一种解决方案
最后给大家看下效果:
我这里是先加载头信息 bb 然后加载的是三种不同的框(下拉框 输入框 两条件一结果框)
二、腾讯template封装数据
这里给大家扩展一个其他的封装数据的方法 template模板引擎框架 这里是在腾讯template基础上使用 些许改变
我用的是template-native-3.0.1.js 大家有兴趣可以找下源码看下
个人认为template用于这些table之类的循环是挺爽的(大佬勿喷)
使用如下:
1.首先 js获取到后台数据列表 通过template进行封装
user.userData = function (param) {
return $.ajax({
url: systemBaseInterface + "/base/userData",
data: param,
failed: function (code, msg) {
DiaLogBox.error(msg);
},
success: function (data) {
template.loadData("user", data.data, function (ele) {
$(ele).show();
user.tableInit();
});
$("#userlist").setPager(data.data, function () {
user.userData(param);
});
}
});
};
2.然后在页面调用方法如下:
页面调用主要分为几步:
a.设置template-name="你在js中设置的名字"
b.循环数据(我这里的list是因为我是分页 最后一层是list目录 然后你们可以看数据情况进行循环)
c.放入数据即可
3.效果如下:
最后给大家放下template-native-3.0.1.js源码 有兴趣看下:
!function () {
function a(a) {
return a.replace(t, "").replace(u, ",").replace(v, "").replace(w, "").replace(x, "").split(/^$|,+/)
}
function b(a) {
return "'" + a.replace(/('|\\)/g, "\\$1").replace(/\r/g, "\\r").replace(/\n/g, "\\n") + "'"
}
function c(c, d) {
function e(a) {
return m += a.split(/\n/).length - 1, k && (a = a.replace(/\s+/g, " ").replace(/<!--.*?-->/g, "")), a && (a = s[1] + b(a) + s[2] + "\n"), a
}
function f(b) {
var c = m;
if (j ? b = j(b, d) : g && (b = b.replace(/\n/g, function () {
return m++, "$line=" + m + ";"
})), 0 === b.indexOf("=")) {
var e = l && !/^=[=#]/.test(b);
if (b = b.replace(/^=[=#]?|[\s;]*$/g, ""), e) {
var f = b.replace(/\s*\([^\)]+\)/, "");
n[f] || /^(include|print)$/.test(f) || (b = "$escape(" + b + ")")
} else b = "$string(" + b + ")";
b = s[1] + b + s[2]
}
return g && (b = "$line=" + c + ";" + b), r(a(b), function (a) {
if (a && !p[a]) {
var b;
b = "print" === a ? u : "include" === a ? v : n[a] ? "$utils." + a : o[a] ? "$helpers." + a : "$data." + a, w += a + "=" + b + ",", p[a] = !0

三、总结
我们页面封装页面及数据的时候大部分时间其实还是页面不用动 然后数据封装用循环遍历 但是你顶不住需求怪呀 但是拼接的话也不是很难 就拿过来页面append()下就可以了 学到三连哈~
