如何让 jqgrid 冻结列与自动换行一起使用 [英] How can i get jqgrid frozen columns to work with word wrap on
问题描述
我正在使用最新的 jqgrid 4.3.1，并且我正在尝试使用冻结列.
问题是我已经覆盖了默认的 css 以支持自动换行(css 解决方案可以看到 ):
第一个 div，命名为 fhDiv，我用黄色标记，其中包含最后一个非冻结列所在的列标题(hDiv)的副本删除.以同样的方式第二个 div，命名为 fbDiv，我用红色标记包含最后一个非冻结列的网格体(bDiv)的副本被删除.您可以阅读包含演示的更新版本:这个.
I am using the latest jqgrid 4.3.1 and i am trying to use frozen columns.
The issue is that i have overridden the default css to support word wrap (css solution can be seen in this question) in jqgrid and i think that is the reason that the frozen columns don't line up correctly with the regular columns. The heights of the frozen rows are not the same as teh heights of the rest of the grid. Here is a screenshot.. the frozen columns are highlighted in the red box (NOTE: i crossed out the content given its not a public site:
Is there anyway to have frozen columns line up with word wrapped cells in jqgrid
NOTE: after trying Oleg's solution below, it works in Firefox but in IE8 I don't see the horizontal scroll bar (see pic)
Firefox:
IE: (notice no horizontal scroll bar)
NOTE:
To help answer Oleg's question, here is a dump of my jqgrid Setup:
jQuery(gridSelector).jqGrid({

var grid = jQuery(gridSelector);

grid.setPostDataItem(prop, value);

filters = $.parseJSON(postData.filters);
newCapture = "Filter: [";
rules = filters.rules;
for (i = 0; i < rules.length; i++) {
rule = rules[i];
op = rule.op; // the code name of the operation
iOp = $.inArray(op, arOps);
if (iOp >= 0 && typeof $.jgrid.search.odata[iOp] !== "undefined") {

fixPositionsOfFrozenDivs.call(this);

//$(gridSelector).jqGrid('navGrid', '#pager', { search: true, cloneToTop: true });
$(gridSelector).jqGrid('filterToolbar', { stringResult: true, searchOnEnter: true });

{ multipleSearch: true,

$('#searchmodfbox_' + $(gridSelector)[0].id).width(560);
}
});
} else {
jQuery(gridSelector).navGrid(pagerSelector,

{ }, { }, { }, { multipleSearch: true,
beforeShowSearch: function($form) {
$('#searchmodfbox_' + $(gridSelector)[0].id).width(560);

});
}
myAddButton(gridSelector, {

}
The implementation of frozen columns in jqGrid are based on creating of two additional divs with absolute position over the standard grid. If the height of all column headers and all rows of the grid's body are the same the frozen columns works good, but in case of variable height (usage of height: auto CSS) one have the following results (see the first demo):
The first div, so named fhDiv, which I marked with yellow color contains the copy of the column header (the hDiv) where the last non-frozen columns are removed. In the same way the second div, so named fbDiv, which I marked with red color contains the copy of the grid body (the bDiv) where the last non-frozen columns are removed. You can read here more about the standard grid elements.
In the demo I used character wrapping in the column headers which I described in the answer and the word wrapping described for example here.
The height of every row of the fhDiv or fbDiv will be calculated independent from the height of non-frozen columns. So the height of the rows can be less as required.
It is difficult to suggest perfect solution of the problem, but it seems that I found good enough pragmatical way. The idea is to set the height of every row from the fhDiv and fbDiv explicitly based on the size of the corresponding row in the main dives hDiv and bDiv. So I extended the code of fixPositionsOfFrozenDivs function described in the answer to the following:
var fixPositionsOfFrozenDivs = function () {
var $rows;
if (typeof this.grid.fbDiv !== "undefined") {
$rows = $('>div>table.ui-jqgrid-btable>tbody>tr', this.grid.bDiv);
$('>table.ui-jqgrid-btable>tbody>tr', this.grid.fbDiv).each(function (i) {
var rowHight = $($rows[i]).height(), rowHightFrozen = $(this).height();
if ($(this).hasClass("jqgrow")) {
$(this).height(rowHight);
rowHightFrozen = $(this).height();
if (rowHight !== rowHightFrozen) {
$(this).height(rowHight + (rowHight - rowHightFrozen));
}
}
});
$(this.grid.fbDiv).height(this.grid.bDiv.clientHeight);
$(this.grid.fbDiv).css($(this.grid.bDiv).position());
}
if (typeof this.grid.fhDiv !== "undefined") {
$rows = $('>div>table.ui-jqgrid-htable>thead>tr', this.grid.hDiv);
$('>table.ui-jqgrid-htable>thead>tr', this.grid.fhDiv).each(function (i) {
var rowHight = $($rows[i]).height(), rowHightFrozen = $(this).height();
$(this).height(rowHight);
rowHightFrozen = $(this).height();
if (rowHight !== rowHightFrozen) {
$(this).height(rowHight + (rowHight - rowHightFrozen));
}
});
$(this.grid.fhDiv).height(this.grid.hDiv.clientHeight);
$(this.grid.fhDiv).css($(this.grid.hDiv).position());
}
};
I called the method inside of resizeStop and loadComplete callbacks. In case of usage of gridResize method one need include additional fixes inside of stop handler.
The full my suggestions you can see on the demo which fixs the results from the first demo to the following:
