DW网页制作中,想让坐上面一条是图片,下面两块区域,左面是一个树形图,右面是内容怎么做?
框架设置应该选择哪一种?上方固定右侧嵌套还是上方固定左侧嵌套?树形图代码应该怎么做···?求大侠指点
提问者采纳
//www。是类似这种吗。://www.codefans.codefans?你看下上方及左侧嵌套树形图
对的!谢谢最后一个问题就是嵌套部分是可被替换成其他界面的是么?如果是最上方显示一个固定图片,正下方插入一个导航条,然后下面分成左侧树形图,右侧是可被替换的显示内容该选择那种示例中的页,导航条该怎么插入,新建个表格么?万分感谢!
框架你选择:上方及左侧嵌套 类型的就行上部导航插入一个新页面,相当于一个包含。&iframe src=&top.html& allowtransparency=&true& width=&1000px& height=&140px& scrolling=&no& frameborder=&0& name=&TopFrame& &&/iframe&top.html就是导航的页面。呵呵,我就是写个例子,你参考下,或是网上找找代码啥的。希望能帮到你

Problem Description
XiaoA lives in a village. Last year flood rained the village. So they decide to move the whole village to the mountain nearby this year. There is no spring in the mountain, so each household could only dig a well or build a water line from other household.
If the household decide to dig a well, the money for the well is the height of their house multiplies X dollar per meter. If the household decide to build a water line from other household, and if the height of which supply water is not lower than the one
which get water, the money of one water line is the Manhattan distance of the two households multiplies Y dollar per meter. Or if the height of which supply water is lower than the one which get water, a water pump is needed except the water line. Z dollar
should be paid for one water pump. In addition,therelation of the households must be considered. Some households may do not allow some other households build a water line from there house. Now given the 3‐dimensional position (a, b, c) of every household the
c of which means height, can you calculate the minimal money the whole village need so that every household has water, or tell the leader if it can’t be done.
Multiple cases.&
First line of each case contains 4 integers n (1&=n&=1000), the number of the households, X (1&=X&=1000), Y (1&=Y&=1000), Z (1&=Z&=1000).&
Each of the next n lines contains 3 integers a, b, c means the position of the i‐ h households, none of them will exceeded 1000.&
Then next n lines describe the relation between the households. The n+i+1‐ h line describes the relation of the i‐ h household. The line will begin with an integer k, and the next k integers are the household numbers that can build a water line from the i‐ h
household.&
If n=X=Y=Z=0, the input ends, and no output for that.&
One integer in one line for each case, the minimal money the whole village need so that every household has water. If the plan does not exist, print “poor XiaoA” in one line.&
Sample Input
2 10 20 30
Sample Output
In &3‐dimensional &space &Manhattan &distance &of &point &A &(x1, &y1, &z1) &and &B(x2, &y2, &z2) &is |x2‐x1|+|y2‐y1|+|z2‐z1|.&

题目大意:一个村庄被洪水摧毁了,整个村庄都要转移。但是山上没有泉水,每户家庭只能
在自家挖一个水井或是修一个水渠从别的家庭引水。如果要修井,则修井费用和房子所在海
拔高度有关,每米X元。如果从别人的家里引水,如果从高于自己家高度的人家里引水,费
用为每米Y元。如果从低于自己家高度的人家里引水,每条要多花费Z元。现在给你这个村庄
N个家庭房屋的坐标(a,b,c)和三种花费X,Y,Z。接着给你各家之间能单向修建引水沟渠的限制。
问:能使全村庄的人喝上水的总修建费用最低为多少。若不能,则输出&poor XiaoA&。
思路:其实就是给你一个有向图,求有向图的最小树形图是多少。但是根结点不确定。在这
里可以假设一个根结点,也就是虚根,让所有家庭都从虚根引水(其实就是每家都自己修井),
所以问题肯定有解,最后就是朱刘算法(模板)直接求最小树形图。
朱刘算法参考我的另一篇博文:
